1022a55665 Somewhat pedantic, but better not to call "hash code" a CRC.

dd1362b69a Rationalize NA contest mode
Generic message packing and unpacking routines now understand antipode
grid contest messages.  These messages  are now recognized as standard
messages in  message response processing and  dealt with appropriately
when contest mode is selected and applicable (currently FT8 and MSK144
only).

fa45380b51 Bring ldpcsim40.f90 up to date and add coherent averaging option to both ldpcsim144 and ldpcsim40. These routines simulate only the performance of the code and the hash/CRC.

ca19e977c0 Add early termination code to the msk144 long-message decoder. Remove references to Radford Neal's ldpc code, which served us well but is no longer needed.

7ba75b79c9 Add routines to decode msk40 and msk144 messages using log-domain belief propagation. Also add new routines to test msk144/msk40 encoding and decoding.
