Lasers must be defined in all microscopes in configuration.yaml in order to be used

[zacsimile]

Tested on the upright. If we have a laser defined in the second microscope in configuration.yaml, but not the first, it will appear in the laser dropdown list for the second microscope only in the GUI. This is good. However, when this unique laser is selected, the last laser to be defined in the first microscope will turn on instead of the selected laser. If the laser is defined in both systems, it works as expected.
