usb serial debug interface & usb serial async msg

[zxkmm]

note

• Don't use MayhemHub since it currently not support real time serial output
• If you don't use this class linker will drop it so it won't use any space
• so delete all debug things before you push your code to production

The logics seems good to me, will be usable in other apps!
Thanks for your work!

@htotoo thank you for your idea and help!
I was originally only planning it to be used on debug :)
😂

[htotoo]

Ohh, let's see what it will be used for ;)

Look good to me.
May need some tests to see if it's stable on the long run.

I'm not opening a convo for that SSTV deleted line ;-p

I'm not opening a convo for that SSTV deleted line ;-p

that file is a little bit weird that I have to delete that line to pass the clang-format check.
And my local clang-format always add that line.
Maybe some rule mismatch (but only exist in sstv related files) it’s weird.
