Steven Franke 9ae479e9d9 1. add error-pattern rejection to osd174 (factor of 3 speedup for norder=3)
2. osd codeword selected based on correlation discrepancy instead of Hamming dist (improves sensitivity)
3. trap zero-valued spectrum values caused by large dt.
4. trap all-zero codeword
4. both decoders return number of hard errors
5. osd174 returns correlation discrepancy (rejection threshold still needs to be tuned).
6. both decoders return the codeword with bits in as-transmitted order, for subtraction.
