[chirp_devel] TM-D710G Driver again

Attached is the latest try at the Kenwood TM-D170/G clone mode driver with py3 compliance. Yes, it does read the entire memory except for the GPS logs. Yes, is still fails two in-valid run_tests processes; leading space in name and bad tones. No, I have not run it under Python3; still trying to get the gi module to import.
