renderer: switched audio rendering over to planar buffers
...
While planar audio cannot be used for playback, it's much easier for processing.
This should lead to cleaner and easier to write code in the future.

decoder/renderer: no longer index automatically as part of the retrieve
...
functions
Indexing is a lengthy process and had a high chance of getting RenderWorkers
stuck doing it rather than being responsive to cache requests. This commit
introduces a system where workers never index media, but instead signal that
media is not ready to their RenderBackends which ensure that the media gets
indexed and re-queues the affected frames when those indexes are ready.

ffmpeg: allow decoders immediate access to frames even while indexing
...
Previously, FFmpeg decoders needed to wait for the initial index to finish
before they could retrieve frames. Now they can retrieve frames while the
index is occurring, provided the appropriate frame has already been indexed (if
not, the retrieve will need to wait still).

ffmpeg: disable multithreading in favor of our own
...
Our renderer system is already heavily multithreaded and prioritized to keep the
main thread active. As a result, FFmpeg receives little benefits from being
multithreaded and is actually detrimental to our main thread as it hasn't been
prioritized to keep the main thread as active as possible.

Since indexing is supplemental, it can be made a background task that can occur
at more or less any time. So we run it as soon as possible.
