[REQUEST]: Support for 4k and bigger resolutions

[FireDragonGameStudio]

Is your feature request related to a problem?

I'm currently implementing cubemap streaming for an immersive spectator mode of my Unity WebRTC package SimpleWebRTC and realized that streaming of Camera and RenderTexture resolutions of 4k and above are currently not possible, due to following workaround:

com.unity.webrtc/Runtime/Scripts/WebRTC.cs

Line 932 in 5f873f2

// Using codec is determined when the Encoder initialization process.

Due to this limitation the streamed cubemap video is always really low-res and pixelated. Is there a plan to remove this limitation and implement the current codec maximum resolution?

Describe the solution you'd like

A way that the limitation of the resolutions are reflected by the selected codec and not forced to be under 4k. This is especially imporant for cubemaps and 360° (stereo) videos.

Describe alternatives you've considered

I tried multiple video streams and stitching them together at the receiving end, but this get's way to complicated and if the videos are not perfectly in sync it's unfortunately not useable.

Additional context

Hey, responded to you at #1085 (comment), regarding this. Just copying that here:
"Instead of going via package manager, just put the runtime folder(https://github.com/Unity-Technologies/com.unity.webrtc/tree/5f873f2ac17f3514ffe8a8514e94bff5e93e3982/Runtime) in your Assets and modify the resolution in Webrtc.cs as you pointed out.
Do watch out for encoder-decoder errors though, there's a reason why that bound is there."
