* Speed up snapshotting of many new dom nodes

By avoiding reflow we shave about 15-25% off our snapshotting time

* Improve newlyAddedElement docs

* Optimize needMaskingText by using el.closest and less recursion

* Serve all rrweb dist files

* Split serializeNode into smaller functions

Makes it easier to profile

* Slow down cpu enhance tracing on fast machines

* Increase timeout

* Perf: only loop through ancestors when they have something to compare to

* Perf: `hasNode` is cheaper than `getMeta`

* Perf: If parents where already checked, no need to do it again

* Perf: reverse for loops are faster

Because they only do the .lenght check once. In this case I don't think we'll see much performance gains if any

* Clean up code

* Perf: check ancestors once with isBlocked

* guessing this might fixes canvas test

* Update packages/rrweb/src/record/observers/canvas/webgl.ts
