Ropebwt3-3.8 (r249)

Notable changes:

• Improvement: a faster algorithm to locate a subset of positions in a suffix
  array interval. Given m highly similar genomes, the expected time is O(s/m)
  where s is the suffix array sample rate.

• New feature: added option mem -p to optionally output a semi-random subset
  of SMEM positions.

• New feature: added auxiliary script rb3tools.js for generating mappability
  filter and for simple SNP calling.
