Update: offloading snapshot export to a task thread
- Stopped exporting binary snapshot, and left a comment explaining why it's not in use (but not deleted)
- Only export compressed json (saves a bit of time on iteration)
Hope is to reduce stutter, but my tests in editor show that it's inconsistent (it's less, but for some reason main thread has frames that somtimes seem to wait for worker thread to finish - need to investigate)
Tests: exported snapshot from craggy, unzipped and loaded in perfetto
