broadinstitute/viral-ngs: v1.17.2

Changed: Improved HiSeq X / HiSeq 4000 compatibility: broken symlinks are now removed from Illumina lane directories if present. This is helpful for HiSeq-X/4000 systems, which write out a single s.locs file for cluster locations rather than per-tile location files. Picard's CheckIlluminaDirectory can create symlinks that take the place of per-tile *.locs files, however these links can break when runs are moved between systems. The change in this release of viral-ngs allows broken links to be removed and corrected. CheckIlluminaDirectory is now called on each call to illumina_demux to check run directories for validity prior to demultiplexin
