Reset VPixx PROPixx Projector

If fast-flicker code has been running, and MATLAB is not exited gracefully/Projector reset, then the displayed projected image may show black and white "ghosting"/double images when the next MEG Operator "wakes" the Projector.
The original fix was to power down the projector completely and then restart.

The following MATLAB code is now used (as a Function) to reset the PROPixx Projector back to its default settings after usage at 1440 Hz.

A file called "RESET_VPIXX.m" can be found on the Stim PC Desktop. Load into MATLAB and Run.

Many thanks to Dr. Alex Zhigalov for the code
