Upgrade to htsjdk 2.19.0 (#77)

* The changes to CRAM have introduced an incompatible change to CRAIEntry that
affects CramSource in Disq. See the note about incompatible CRAM changes
at https://github.com/samtools/htsjdk/releases/tag/2.17.0.

This commit uses the new CRAIEntry API introduced in samtools/htsjdk#1256

* Convert catch for EOFException -> RuntimeEOFException

* Use htsjdk 2.19.0
