Changes for Build #424
[Jim Unroe <rock.unroe at gmail.com>] [UV-5R] Add Support for UV-6 with Longer 12 byte Ident

The currently shipping Baofeng UV-6 responds to the clone request by
returning a 12 byte "ident". The original model replies with an 8 byte "ident"
(the same as all other radios currently supported by the uv5r.py driver).

The current CHIRP driver appends the radio's memory image after the "ident"
so the settings structures are all offset by 8 bytes to accomodate these extra
bytes at the beginning of the image. So there must alway be exactly 8 bytes
prepended to the actual memory map data.

Original UV-6 ident:
AA 36 74 04 00 05 20 DD

New UV-6 ident:
AA 01 01 36 01 74 01 04 00 05 20 DD

This patch works around the issue by doing the following...

1. The "ident" is now read one byte at a time until the last byte ("\xdd")
   is received. This make it compatible with an 8 byte and 12 byte "ident".
2. The 4 bytes of the ident containing "\x01" are discarded to shorten the
   ident to the standard 8 byte length and to put the "ident" in the same
   format as the "ident" of the other radio models.
