Many improvements to ft2, including:
...
- SNR displayed on decode line
- Separate transmit() subroutine
- Output sent to all_ft2.txt
- Display Rx level (hit L to toggle On/Off)
- Auto-sequencing (hit A to toggle On/Off)

More work on FT2. New frame format is 16sync + 128codeword. Data chunk is assumed to be 2.5s long. A rudimentary sync routine is implemented which finds the single strongest signal.
