KVMD + uStreamer performance update

Today I have prepared a great update for you. After few weeks of research, I managed to increase the video performance slightly reduce the latency for all CSI devices (PiKVM V4, V3 and CSI-based V2).

In H.264 mode (WebUI and VNC), you will get stable 30fps on 1080p and 60fps on 720p In MJPEG mode it just works a little faster.

To update:

# pikvm-update`
