- add support for the shift button
- many code cleanups and improvements

Sessions of UART capture of the reference HP34970A unit.

In these capture frames:
- RX: FP -> CPU
- TX: CPU -> FP

Example extraction of data:

  sigrok-cli -i startup-no-key -P uart:baudrate=187500:parity=even:rx=RX:tx=TX \
             --channels RX,TX  -A uart=rx-data:tx-data:rx-start

Start-bit: following code is a RX, so generated by the FP.
