Add UniqueId.uidToLong() and longToUID() helper methods for converting UIDs
Moved addId() from TsdbQuery to UniqueId.addIdToRegexp() as I need it elsewhere
Renamed UniqueId.getTagPairsFromTSUID() to getTagsFromTSUID() since that's what
the method actually did, it didn't return pairs, rather individual UIDs.
Also removed the UID widths from getTagsFromTSUID() since they're now statically
accessible from the TSDB class. Modified all callers as well.
Add UniqueId.getTagPairsFromTSUID() with string and byte parameters that does
what it's supposed to, returns pairs of tag UIDs from a TSUID
