v2.1.1

Summary:
Fixes an issue with calculating currents with TPXO9-atlas-v5 models (thanks @maucollu!). Refactors the high-level compute functions into single module (compute.py). Moves the ellipsoidal parameters to datum function within the crs.py module. Adds further improvements to the overall documentation and lots of small fixes.
