Move most of RelayPool away from the Main Thread

Browse Source 
This is a large refactor that aims to improve performance by offloading
RelayPool computations into a separate actor outside the main thread.

This should reduce congestion on the main thread and thus improve UI
performance.

Also, the internal subscription callback mechanism was changed to use
AsyncStreams to prevent race conditions newly found in that area of the
code.

Changelog-Fixed: Added performance improvements to timeline scrolling
