Two changes:
- It seems that Illumina version numbers are dotted and that the
dashed version in the 2.18... filename is an anomaly (based on the
names for 2.17.1.14 and 2.19.0). `url_for_version` does the right
thing for 2.18. It will need to be fixed when support for 2.19 is
added. 2.17 is no longer generally available so it gets a pass.
- Add version and hash for 2.17.1.14.
2.17.1.14 is no longer distributed. If you have a copy of the
source tarball, you can drop it into a local mirror w/ the name
mirror/bcl2fastq2/bcl2fastq2-2.17.1.14.zip and go from there.
