Changes for Build #669
[Jim Unroe <rock.unroe at gmail.com>] [th-uv88] Add settings to TYT TH-UV88

This patch adds the remaing settings from the OEM "Basic" settings page.
- Radio Moni
- End_Tone_elim
- SW Audio
- Scan Type
- Key Lock
- Key Mode
- Intro Screen

Also firmware BQ1.41+ allows the radio to independently select MR/VFO mode on

#9581

[Dan Smith <dsmith at danplanet.com>] Make test adapter granular

This makes the unit test adapter granular so you can run individual
tests and drivers for quicker automated testing.

[Dan Smith <dsmith at danplanet.com>] Add test images for #8123 #9559 #9217

[Jim Unroe <rock.unroe at gmail.com>] [UV-5X3] Add saved VFOs to BTECH UV-5X3

It was discovered that the BTECH UV-5X3 has 3 memories for each VFO display
line that can save frequencies, one for each of the 3 bands (VHF/VHF2/UHF).
Tapping the [BAND] button of the radio will cycle through the 3 memories
associated with the selected display line and place the currently selected
memory into the currently selected VFO.

This patch adds support to allow the viewing/editing of these 6 memories.
