Add support for lyx omicron laser

[gjover]

We have a Lyx opmicron laser and we need to integrate it in our system.

There is support for the Omicron deepstar (see microscope.lights.deepstar.DeepstarLaser). Is the interface to Omicron Lyx much (or any) different?

[gjover]

Yes, the command set is different.

I upload the last version once it has been tested. I guess that both devices could be merged and some parts could be generalized.
