1.1

Most all GET ops and processing now can happen in a background web worker thread (if enabled), less blocking on main thread.

Inlining and better loop unrolls for faster bit ops. (main thread / normal use)

Improved logging.

Moved try/catch out of main functions so doesn't block V8 optimizations.

Added old cache detection and purging.

Bugfix for max idx z constraint not being enforced.
