Add optional version command to launcher

[marcelldls]

version is a useful cli command - this option adds the command if the developer passes a version that should be output when executing ${my_fastcs_device} version

Would it be possible to print the FastCS version as well as the controller version?

[marcelldls]

Thats a good idea

[marcelldls]

The default is that it will print FastCS version. If a version of the implemented controller is passed, it will also be shown

(.venv) [esq51579@pc0146 FastCS]$ thorlabs-mff-fastcs version
INFO: PVXS QSRV2 is loaded, permitted, and ENABLED.
ThorlabsMFF: my_version
FastCS: 0.7.1.dev19+gdc6f1a0

[GDYendell]

Looks good.

Note if we move towards having a single FastCS application entry point then it will need to import the controller and could potentially get the controller version itself.
