Release 23.01

[svpcom]

This release include major protocol changes and incompatible with previous releases.

Changes:

1. FEC settings now embedded into session packet. This means that RX get FEC type, K and N from TX. This allows to add dynamic FEC in future without protocol change and allows different FEC settings for uplink and downlink (this settings now in TX sections only)
2. Small tunneled IP packets now aggregated the same way as mavlink packets. This raise performance for interactive TCP sessions via tunnel.

Raspberry PI 3B ready to use image:

Changes:

1. RTSP server now enabled by default. So you can see video simultaneously on RPI (via HDMI) and on laptop via QGC
2. In rtl8812au driver was added a patch that drop tx packets while medium is busy and internal hardware queue overflows. This allows to reduce latency by avoid sending stale data and increase FEC efficiency.

• This image was tested on RPI3b + Alfa AWUS036ACH + PI Camera. Use native ("thick") USB3 cable from this card. If you have issues with different HW setup then try to test this setup first before issuing bug report.
• OSD will not work on RPI4 due to dropped OpenVG support.
• If you use high-power cards like "taobao card" then you must use external high-current power supply and low-esr capacitor on the card. Don't power them from USB!

Will it work RPI 4B?
Tried to start it, but there's no wifi driver...
