Consolidate Power Supplies

[AdvancedImagingUTSW]

To enable dissemination of the system and improve the ease at which people can build it, we should consider replacing the power supply for the resonant galvo.

ASI has Tiger low-noise power supply modules that they use for traditional galvos. Currently they offer +/- 15V with either 3A or 6A outputs. They think they can do +/- 12V or just 12V pretty easily by changing a single component but need to double-check.

It is worth noting that our resonant galvos are increasingly difficult to get, and a future build may need to have a standard galvo. At which point, the power supply options would change.
