Add a series of reference serial data sessions from a working 34970A unit. draft

• Sun, 01 Nov 2020 22:16:33 +0100
• by David Douard <david.douard@sdf3.org> [Sun, 01 Nov 2020 22:16:33 +0100] rev 43
• Add a series of reference serial data sessions from a working 34970A unit.
  
  These sessions do have a few glitches, however (random off by one bit,
  probably due to a sampling freq a bit too low).
  
  Comes with an adapted version of the uart_filter.py script to interpret the
  communication protocol.
