Fix some indexing problems. Create subroutine ft2_gfsk_iwave.f90 for use with ft2.exe. Needs testing.

ft2sim now creates a GFSK waveform with BT=1.0. It also adds raised cosine ramp up and down at the beginning and end of the transmission.

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.

In ft8apset, mycall and dxcall must be at least 3 characters long, otherwise they are treated as non-existent.

Try harder to ensure that we don't waste time trying to do ap decoding that would involve nonstandard calls. Current code does not support ap decoding with non-standard calls.

Use separate hash tables for 10, 12, and 22 bit hashes. Make unpacking i3=4 messages depend on whether unpack is being done on a received message, or a to-be-transmitted message. Give mycall13 priority over hash table entries in certain contexts.
