Features
*************
- Added stat in stats panel to show currently used audio/video codec.
- Added audio bitrate in the stats panel.
- Added toggle in the settings panel to force mono audio.
- Added new info in stats panel to indicate input controlling mode.
- Added Linux platform scripts for the Matchmaker/SFU.
- Added npm commands for signalling server. `npm run $config -- $args` which will work across platforms (`$config` might be `start-signalling-server` and args might be `--debug`)
*************
Bugfixes
*************
- Fix matchmaker taking up to 45 seconds to display a valid server for use.
- Fix regression where all browser audio was mono (default now stereo).
- Fix Linux SFU and Signalling Server scripts not grabbing the public IP correctly.
- Fix linux setup scripts not working when being run from a location that has a space in the path.
- Fix SFU run_cloud.bat tries to call non-existent run.bat.
- Fix being unable to type in console of a streamed application.
- Fix docker scripts running only TURN when we needed both TURN and cirrus.
- Fix docker scripts not starting correctly.

Refactor player sessions
Fix PixelStreamingAudioComponent had delayed audio.
Fix audio bitrate from Unreal Engine to browser was set to a low default causing compressed audio quality in stream. The new default is now Opus maximum value of 510kb/s.
Fix the Selective Forwarding Unit (SFU) not being added to the Pixel Streaming samples folder for a packaged project
Fix default max bitrate not being high enough to support 4k.
Fix reconnections not autoplaying in the browser.
Add datachannel support to SFU.
Add WebRTC c++ client behaviour to pixel streaming system. This is used for developing unit tests.
Add a unit test that will start streaming, connect a client and check that a data channel message can be sent.
Add the ability for a user to start/stop streaming as needed through the use of PixelStreaming.StartStreaming and PixelStreaming.StopStreaming
Add the ability for the stream resolution to be changed at runtime
Notes: AVEncoder no longer stores a width and height; These properties have been moved to the FVideoEncoderInput. This input is now the source of truth and both AMF and NVENC will adapt their resolution to the input resolution.

/?preferSFU which lets the user indicate whether they would like to try to connect to the SFU,
/?ForceTURN which lets the user indicate they will only make a peer connection using a relay candidate (this is useful on Chrome when debugging TURN servers),
/?useMic which lets the user indicate they would like to use their microphone to send audio back into Unreal Engine, which can be then be consumed by a PixelStreamingAudioComponent in the scene.

- Stats can now be queried.
- Stats can be listened to for changes using IPixelStreamingModule::AddAnyStatChangedCallback.
- Web frontend stats/settings cleaned up to reflect only important settings a user can change.
- Removed latency tester in favour of a stats report.

- Improve JS logging with formatting and colouring, removed redundant logs.
- Added url parameter ?ForceTURN because Firefox method of forcing TURN seems problematic and Chrome does not have a method to force TURN.
