simple jack client to invert channels.  when using a soundcard dac correction amp all channels are inverted by the amp and this corrects that.
finish RGB color support for output and simulator
small cal program for setting correction amp levels
make for cal program
add separate power setting for each color
change cal program to output a sine save on the color channels.  easier to set min and max voltate.
separate offset and delay by color
enable color for playilda tool
Rework color analog offsets to allow a seperate blanking level and minimum level.  This allows keeping the laser warm with a blanking current level and then setting a different point to be the lower limit of that color.
output:
  allow each color channel to be turned on and off separately
  add setting for TTL or analog color channels
  add setting for RGB or single color laser projector
  put enforce safety toggle option back in
quick hack in some color to lase_demo
