Static-aware, key-less, component-based, cached range APIs.
```rust
let caches = re_query_cache2::Caches::new(&store);
// First, get the raw results for this query.
//
// They might or might not already be cached. We won't know for sure until we try to access
// each individual component's data below.
let results: CachedRangeResults = caches.range(
&store,
&query,
&entity_path.into(),
MyPoints::all_components().iter().copied(), // no generics!
);
// Then, grab the results for each individual components.
// * `get_required` returns an error if the component batch is missing
// * `get_or_empty` returns an empty set of results if the component if missing
// * `get` returns an option
//
// At this point we still don't know whether they are cached or not. That's the next step.
let all_points: &CachedRangeComponentResults = results.get_required(MyPoint::name())?;
let all_colors: &CachedRangeComponentResults = results.get_or_empty(MyColor::name());
let all_labels: &CachedRangeComponentResults = results.get_or_empty(MyLabel::name());
// Then comes the time to resolve/convert and deserialize the data.
// These steps have to be done together for efficiency reasons.
//
// That's when caching comes into play.
// If the data has already been accessed in the past, then this will just grab the
// pre-deserialized, pre-resolved/pre-converted result from the cache.
// Otherwise, this will trigger a deserialization and cache the result for next time.
let all_points = all_points.to_dense::<MyPoint>(&resolver);
let all_colors = all_colors.to_dense::<MyColor>(&resolver);
let all_labels = all_labels.to_dense::<MyLabel>(&resolver);
// The cache might not have been able to resolve and deserialize the entire dataset across all
// available timestamps.
//
// We can use the following APIs to check the status of the front and back sides of the data range.
//
// E.g. it is possible that the front-side of the range is still waiting for pending data while
// the back-side has been fully loaded.
assert!(matches!(
all_points.status(),
(PromiseResult::Ready(()), PromiseResult::Ready(()))
));
// Zip the results together using a stateful time-based join.
let all_frames = range_zip_1x2(
all_points.range_indexed(),
all_colors.range_indexed(),
all_labels.range_indexed(),
);
// Then comes the time to resolve/convert and deserialize the data, _for each timestamp_.
// These steps have to be done together for efficiency reasons.
//
// Both the resolution and deserialization steps might fail, which is why this returns a `Result<Result<T>>`.
// Use `PromiseResult::flatten` to simplify it down to a single result.
eprintln!("results:");
for ((data_time, row_id), points, colors, labels) in all_frames {
let colors = colors.unwrap_or(&[]);
let color_default_fn = || {
static DEFAULT: MyColor = MyColor(0xFF00FFFF);
&DEFAULT
};
let labels = labels.unwrap_or(&[]).iter().cloned().map(Some);
let label_default_fn = || None;
// With the data now fully resolved/converted and deserialized, the joining logic can be
// applied.
//
// In most cases this will be either a clamped zip, or no joining at all.
let results = clamped_zip_1x2(points, colors, color_default_fn, labels, label_default_fn)
.collect_vec();
eprintln!("{data_time:?} @ {row_id}:\n {results:?}");
}

Text logs, line plots and scatter plots.

Migrate all spatial views that were using the old cache APIs to the new ones. Instance keys are not queried at all anymore. All views are now range-aware by default. Also took the opportunity to somewhat streamline everything. The 10min air-traffic example with full visible range is about 2-2.5x faster than before. I'm sure I broke a few things here and there, I'll run a full check suite once everything's said and done. --- Part of a PR series to completely revamp the data APIs in preparation for the removal of instance keys and the introduction of promises: - #5573 - #5574 - #5581 - #5605 - #5606 - #5633 - #5673 - #5679 - #5687 - #5755 - #5990 - #5992 - #5993 - #5994 - #6035 - #6036 - #6037 Builds on top of the static data PR series: - #5534

Migrate every little thing that didn't use to go through the cached APIs. `Image` and `Mesh3D` are temporarily cached even though they shouldn't be, that's taken care of in a follow-up PR. Once again, I probably broke a million edge cases -- I want to get as fast as possible to removing instance keys before doing an in-depth quality pass. --- Part of a PR series to completely revamp the data APIs in preparation for the removal of instance keys and the introduction of promises: - #5573 - #5574 - #5581 - #5605 - #5606 - #5633 - #5673 - #5679 - #5687 - #5755 - #5990 - #5992 - #5993 - #5994 - #6035 - #6036 - #6037 Builds on top of the static data PR series: - #5534

There is now only one way to query data: `re_query` (well you can still query the datastore directly if you're a monster, but that's for another PR). All queries go through both the query cache and the deserialization cache. There will be a follow-up PR to disable the deserialization cache for specific components. Most of this is just (re)moving stuff around except for the last two commits which take care of porting the cached test suites since they cannot depend on uncached APIs to do comparisons anymore. - Closes #6018 - Closes #3320 --- Part of a PR series to completely revamp the data APIs in preparation for the removal of instance keys and the introduction of promises: - #5573 - #5574 - #5581 - #5605 - #5606 - #5633 - #5673 - #5679 - #5687 - #5755 - #5990 - #5992 - #5993 - #5994 - #6035 - #6036 - #6037 Builds on top of the static data PR series: - #5534
