Add proper color keying to tracker-pt

Instead of just selecting the red/green/blue channels, also subtract the
other channels. This allows for point tracking with just colored spots,
rather than IR LEDs -- green and magenta work particularly well for
this.

This keeps the existing "Red/Green/Blue only" options, but adds
"Red/Green/Blue/Cyan/Yellow/Magenta filter" options, which do a better
job of isolating those colors.
