Fixing the alignment of our FFmpegReader video buffers to be 32 / AVX2. This increases performance by a factor of 3X.

Small improvement to caching sws scale context and reusing AVFrame objects. About 1.5% less CPU calls, and more even memory allocations (less spikey).

Adding spherical support to FFmpegWriter and FFmpegReader, so they can optionally write the correct side data for Spacial and equirectangular 360 videos.

Large refactor of FFmpegReader ProcessAudioPacket to allow FFmpeg to convert sample values into floats (AV_SAMPLE_FMT_FLTP), each channel in it's own data buffer, which makes it easy to pass to Frame::AddAudio.

Fix webm packet reading, to correctly retry packets. Sometimes we must send more packets before receiving decoded data, and sometimes we need to receive more decoded data before sending more packets. We had a logic error in this code.

Many improvements for smooth audio playback when 'time' keyframes are used for time remapping.
...
- Added new Frame::ReverseAudio() helper method - for time keyframe support playing backwards audio
- Fixed math rounding error on time keyframe Resampler, to use the rounded source samples value
- Removed some unused args and Frame audio methods
- Reset FrameMapper resample context when non-adjacent frames are requested
- Correctly reverse Frame audio if a time keyframe is present, and reversing audio
- Rewrite Keyframe::IsIncreasing() function, to give accurate direction of time keyframes at any index (special logic to support first and last indexes)
- Fixed Keyframe unit tests - since logic has changed a bit
- Improved time mapping unit tests
- Replace many c-style casts with static_cast
- Added new sine.wav test file

- Clip reader init should consider paths with a % to use FFmpegReader by default (i.e. image sequences)
...
- FFmpegReader info struct should not be initialized during Open() after it is initially populated - so our SetJson() method can properly override it's values
- FrameMapper Json() method should include it's mapped Reader JSON - even though it is not yet possible to read it back in yet
- New unit tests for Timeline ApplyJsonDiff, and verification that we can override FFmpegReader info struct (i.e. updating FPS, time bases, etc...)
- Some whitespace fixes

Allow waveform generation to happen before Clip effects are processed. Also, allow the Caption effect to add image data (i.e. waveform graphic) and allow Clip to detect that image to output it correctly. The result of all this: audio-only files now support the Caption effect, on top of the generated waveform image. Lastly, generated waveforms should use the entire Timeline size - and not a pre-determined 720x480 size.
