Free running camera API for Orca camera

FEATURE: Free running camera API

Is your feature request related to a problem? Please describe.

Sometimes it is needed to run the camera on the free run so optical engineers can tweak and align their systems to their preference while observing changes on the camera on-the-fly. Here I am proposing a feature to address this need.

Describe the solution you'd like

Having a simple API where one can call something like camera.free_run() which starts camera on the free running mode and starts a viewer with the streamed camera images.

Describe alternatives you've considered

No compelling alternative.
Using HCImage software but not a compelling option.

Assigned to you @xiyuyi, please let me know if you have any questions.

[xiyuyi]

this is done. We can now move on and think about how to clean it up to match the standard for coPylot.

[AhmetCanSolak]

we will merge some of it in #135 , and we can make a couple other PRs together @xiyuyi to introduce all of your changes to the main branch.
