+ - 'hf mfu dumop / read'  - now retries five times. (@jamchamb)
  - Added `hf list mf` - deciphers crypto1 stream and works with first authentication and weak nested authentications (@Merlok)
  - Adjusted `lf cmdread` to respond to client when complete and the client will then automatically call `data samples` (@marshmellow42)
  - Added a bitbang mode to `lf cmdread` if delay is 0 the cmd bits turn off and on the antenna with 0 and 1 respectively (@marshmellow42)
