f64cfb68ec 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.

808259b7bf 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.

f75c90fd3e Add routines to decode msk40 and msk144 messages using log-domain belief propagation. Also add new routines to test msk144/msk40 encoding and decoding.
