On DAQs with >2 analog outputs, optionally use one for laser blanking (and intensity control).
For now, we assume the laser is controlled by an EOM (or similar device) through a command voltage. Off = 0 V, On = user-selected voltage.
Max voltage should probably also be configurable (type 1V or 2V).
We need to assume the EOM will take several pixels' worth of time to fully switch, so an extra (adjustable) margin is needed before and after the scan line.
(Blanking via a digital output might also be useful in some cases. Consider if/when the need arises.)
Probably best to resolve #30 before adding this, but in principle #30 is not a prerequisite, since the blanking only needs to be synchronized with acquisition.
