I created a temporary version u/rowen/log_move_code without requiring a ts_xml update using branch u/rowen/log_move_code and tag v1.3.5.alpha.1

Please run this and give me the information when you see commands failing to be reported as done and/or failure to report "in position".

Please do not merge it to develop.

I also:

• Updated the code to use a new public MoveCode enum class.
• Overhauled the code in the mock controller that computes the move code (including fixing a race condition).
• Fixed some errors in test_csc.py (errors which suggest that the simulator was not outputting the correct move codes).
• Enhanced test_csc.py to test the new moveCode event.

See comments in ts_ATDome. Improved code readibility, adds event with controller internal state.

Thank you for the helpful review. I updated to use |= to accumulate mask values in the mock controller, as you sensibly suggested. I am not ready to add the MoveCode enum to ts_xml and ts_idl because I consider the mask event an internal detail that is only exposed for debugging purposes, and it is a value that may change or go away. I am loath to make it easier to interpret lest clients start using it.
