Optofidelity: PWM proof line detector

The new line detector returns the current left and right location of the
line during video processing and then using the nputil filters to
determine line draws.
Since we are processing the whole dataset at once instead of frame by
frame, we have more possibilities to work with noise caused by PWM
artifacts.
The LineDelegate also activates active pwm compensation which reduces
artifacts to near zero.
