Add support for BTECH DMR-6X2 Pro

[hmatuschek]

This device identifies itself as "D6X2UV2" with hardware revision V100 (1.00).

This device is very likely almost identical to the D878UVII, so "only" the codeplug format needs to be verified:

• Verify memory regions
• Verify channel encoding
• Verify zone encoding
• Verify contact encoding
• Verify analog contact encoding
• Verify scan list encoding
• Verify radio DMR ID encoding
• Verify DMR APRS encoding
• Verify general settings encoding
• Verify boot settings encoding
• Verify preset messages encoding
• Verify hot key settings encoding
• Verify FM broadcast channel encoding
• Verfy analog signalling (DTMF, 5-tone etc) encoding
• Verify DMR encryption encoding
• Verify call-sign DB encoding.

Development will happen in the d6x2uv2 branch. There is also an emulator script under doc/reveng/btech/d6x2uv2/, if you like to assist in the reverse engineering of the codeplug format.

Please let me know what I can do to help!

Is that the same model as in #335 ?

Yes, it is. There is a different CPS for that device, so it might have some differences in the codeplug. I "just" need to verify the codeplug format first and then I can support it. However, as usual for AnyTone-type radios, it is a lot of work. So I would like to complete the support for the existing devices before I support new ones.

Very much understandable! I was just wondering if there are two open issues - oh, no, one is a "discussion". Thanks for all your effort!

Keep up the great work!
