Ropebwt3-3.3 (r149)

Notable changes in the sw command:

• New feature: option to try SW only when there is a long MEM. This is not
  enabled by default.

• New feature: option to output unmapped reads in PAF

• Bugfix: backtracking the F state could be wrong in corner cases

• Bugfix: coordinates on the reverse strand were not flipped in PAF

• Breaking: don't output the reference sequence in the rs tag by default

Other new features:

• New feature: added the stat command to report the number of runs. Only
  working for the FMD format for now.

• New feature: added --min-gap to the mem command to output regions not
  covered by long MEMs.
