I'd argue that's different - we don't know if it's an error unknown, instead it is an error that we literally don't know about

What
Introduces a very simple
rerun::Result. I decided to keep it a lot more simple than the arrow Result type and refrained from the typical "return or assign" etc. macro since I noticed that they get quite complicated quickly.The idea is that the rerun result type won't be needed by a lot of manual code, so erring on the too lightweight side should be in our favor.
We use this now accross the entire public serialization path - meaning that once we move out array->arrow serialization helper into separate headers we should be pretty much done with not exposing arrow headers!
