Ropebwt3-3.1 (r77)

Notable changes:

• New feature: the match command supports multi-threading.

• Improvement: generating suffix arrays (SA) with libsais16x64, a new addition
  to libsais by @IlyaGrebnov. libsais16x64 is faster and uses less memory for
  multi-string SA construction than libsais64. This reduces the peak memory of
  ropebwt3 for human genomes.
