Alignment module/subpackage

[AhmetCanSolak]

Upon discussion with @xiyuyi about alignment needs(summary can be found in #96 ), in this PR I wanted to discuss and implements the needed APIs and make our alignment work easier and lighter.

The structure appear useful at the current stage. Before merging, perhaps having a collection of more intuitive demo or test codes would be helpful.

We would also need the API the following devices:
Motorized actuator from Thorlabs.
Hamamatsu camera.
Motorized stage (ASI).
Thorlabs inspection camera (sCMOS).

We already have what is needed for ASI stage and hamamatsu camera(can make the final API nicer though). For the Thorlabs devices, could you share the specific devices you want to use @xiyuyi ?
