lrSv/srSv: human-readable SV type filter labels, script cleanups

Add human-readable labels to the supertrack-level svType filter on
both the lrSv and srSv supertracks using the "CODE|CODE (Long name)"
filterValues syntax: DEL -> "DEL (Deletion)", INS -> "INS (Insertion)",
etc. Labels keep the short code up front so users can match what
hgTracks shows next to each feature.

Also sweep in the in-progress converter/as-file cleanups under
scripts/lrSv/ and scripts/srSv/ (introduction of lrSvCommon.py
helpers, consistent insLen / svLen / AC column naming, tightened
field-description text) that had been piling up as an unstaged
working tree.
