Fix python binding (3.10)

[jwmelto]

From maint-3.10 branch, run make install.

bash-4.2$ python -c 'import CyberRadio'
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/opt/foss/lib64/python3.8/site-packages/CyberRadio/__init__.py", line 24, in <module>

    import CyberRadioDriver as crd
ModuleNotFoundError: No module named 'CyberRadioDriver'

If the driver isn't (currently) supported in the 3.10 branch, then it should not be imported in the wrapper code.

I need to upload the Python3 version of the CyberRadioDriver. It will be here in a couple hours

I see you've made an update, but there are no (usable) build instructions. makedeb and makerpm are your internal tools?

I'll fix the master branch README, but maint-3.10 has all the right stuff: Here

I can't make sense of it, but maybe you can. Possibly the control block is included from another block?
(I have no controll block; just a vita_udp_rx block)

It doesn't seem to have any negative effect, but I'd prefer not to have "normal" errors.

I think this stems from not having quotes around the label. I'll fix in next update with #12
