Release v2.8.0

This release improves support for BEDPE and arc rendering of structural variants.

It also adds a new CLI command called jbrowse sort-gff that intends to help simplify the loading of GFF tabix tracks.

Usage:

jbrowse sort-gff yourfile.gff | bgzip > yourfile.sorted.gff.gz
tabix yourfile.sorted.gff.gz
jbrowse add-track yourfile.sorted.gff.gz --load copy --out /var/www/html/jbrowse2

The jbrowse CLI tool can load BEDPE files with simply jbrowse add-track yourfile.bedpe (or, optionally gzipped e.g. yourfile.bedpe.gz)

Screenshot showing the same data rendered as both a BEDPE file and VCF file with different variant types (<DUP>, <DEL>, <INV>, <TRA>). Notably, this arc rendering can render 'cross-region' or 'inter-chromosomal' arcs.
