PR-705 support and a slight update to the monitor calibration routines

1. PR-705 toolbox
    * Follows a similar format to the other toolboxes
        * Open and close remote communication
        * Read and write data
        * Take spectral measurements
        * Change the meter's configuration 
    * Added PR-705 support to CalibrateMonSpd and its dependencies.
2. Calibration update
    * Replaced the CLUT drawing method in favor of specifying the RGB directly
    * CalibrateMonDrvr: Randomized the gamma and the guns
        * We saw calibration weirdness when the guns weren't randomized
