Modify Allied Vision Camera service to make it work with the new VimbaX software

Fixes #223 and https://github.com/ivalaginja/thd-controls/issues/108.

I tested the VimbaX migration on the THD2 testbed.
After installing everything that is required on the thd-controller PC, I did some testes and the required changes in the service.
I also updated the documentation file.

What are the concrete tests you ran to make sure the migration works and does not introduce any issues?

For now, I opened the service in a terminal, and sent some commands though an ipython terminal. I also opened the GUI and the corresponding viewer, to go and test to change the exposure time, the width of the frame, ...

Ok great! Could you also run some of the example scripts over in thd-controls to make sure they run without any problem? I want to make sure there's no detail we didn't catch in this transition, even if it looks very non-invasive.

I ran some further tests on the Allied Vision Cameras (the visitor camera and LOWFS camera).
1 - the take_exposure.py example. Here is a screenshot of the result, the test is successful.

2 - the take_calibrated_image.py example. Here is a screenshot of the result, the test is successful (even if the image is saturated !)

3 - I ran the autoexpose function, with the autoexpose_test script. The result was 252.485 us for target 0.5 and 15 percent. It is coherent and the wanted result.
4 - Finally, I ran the TT controller loop on the LOWFS camera, and it worked too :)

All tests are successful and the migration to VimbaX doesn't seem to cause any problem and the Allied Vision Cameras.

Excellent, thanks for all the detailed test results! This is good to go.
