CHIRP

Please add support for Retevis H-777 v3.0 (SKU A9294C). The most notable physical difference in this model is a USB-C charging port in the radio (below the speaker mic connections). Model has other other features that the previous version did not have:

*one-button cloning
*scan function can be assigned to PF2 (long press) instead of Ch-16
*improved alarm function (PF1 long press)

Details:
1) Older version (SKU 9104H) works with "H777" profile so it is not a cable issue
2) Tried all H777 profiles currently available and none worked (debug log attached)
3) No .img file of the radio available since it is not able to connect
4) Confirmed able to read/write to radio using manufacturer software
5) Asked on mailing list and directed to create request after explaining all above (Re: Retevis H777 Unable to Connect)
