- CreateInputDevice is only called once on a module so it cannot be used to create multiple input devices when we're creating mutliple streamers. Only the default will work since it's the first being made.
- Fixing signalling config loading when it is readonly.

*************
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.
*************

One meaningful difference is that anyone who has depending on the old behaviour where a new streamer would override an existing one will have to change their setup.
This fixes the problem where the SFU crashes if multiple streamers attempt to connect.

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.
