Switched from deque to a set to greatly increase preformance in abstract ltm.  Added a new Bitmask remapper that's much faster for a sequential mask.  Started work on a parallel timeline.  Fixed invalid assertions in bitmask lite tests.  Started rework on the gauntlet test.

Updated some of the older bitmask functions to allow different option types.  Updated more code to work with Spark bitmask rows.  Fixed an issue with join_bitmask where it was not getting the last interval, added test and updated another.  Added code to convert a EnhancedBitmaskLike to hex.
