Update MT99xx_ccnrf.ino

[rdba2k]

add QF009 Su35 support to MT99XX protocol / H7 sub protocol

[rdba2k]

It is going to be replaced by better code

[pascallanger]

The code has proposed won't work anymore for the H7...
packet[6] |= FLAG_MT_RATE1; -> it's taking the packet[6] previous flags which you are overwriting with your new code

I realized the issue. I will work on adding a new sub protocol Su35 but my code is not working yet.

I am thinking in MT99xx_ccnrf.ino

add
#define MT99XX2_SUB_BASE 0x10

so this will change to
if(protocol == PROTO_MT99XX2)
sub_protocol|=0x08; -> sub_protocol |=MT99XX2_SUB_BASE;

and all
PA18+8 -> PA18 | MT99XX2_SUB_BASE

Thus leaving subprotocol "8" to Su35.

Or you can made the change and I will learn what are the changes needed.

Thanks.
