add Sort::strverscmp
use strverssort instead of nsort

nsort, from Sort::Naturally, has a different sort preference compared to
JoinX which uses GNU strverscmp.
Merge branch 'RT/91739'

CHANGELOG: New sort order in `gmt bed chrom-sort` which is used as the default
sorter in DV2.  This will correct a sort incompatability between some DV2
results and JoinX.  Any existing DV2 results affected by the sort
incompatability will need to be set aside.  If you get a sort error from JoinX
like 'Unsorted data found in stream...' then your DV2 results may be affected.
Currently only builds that use GRCh37-lite-+-HPV_Redux-build (116426356) are
known to be affected.
use throws_ok instead of eval
