Update NM-64 antenna positions

Antenna mapping was wrong. Have implemented mapping from LWA memo 200, with data from LSL-1.0.0

Also updated cable delay and phase to source code. This still needs a lot of testing, may have to simulate dataset in order to do this properly.

Fixed indexing in qtuv.py, where phase plots were displaying wrong.
