Pixel OSD/FrskyOSD support request

[zigomatichub]

Some FC board use FrSkyOSD. It's supported in BF but seems not in EmuFly, then OSD is empty.

Example board http://www.mateksys.com/?portfolio=f722-px

It may be possible to port the code from BF to Emu easily ? I think it's link to this : https://github.com/betaflight/betaflight/pull/10702

Thank you
