Enable CCD update from installed package

[davegrays]

currently the setup_ccd.py script has to be run from a clone of the repo. this creates a command-line utility to run the ccd update directly from the pip installed package itself. i think this simplifies dependency management for downstream projects quite a bit

This sound indeed like a good idea, I have not thought about, yet. From my perspective the most important point is, that it cleans up the install-setup-install dance required now. I will give it a few days to think about possible caveats, we might have missed. But otherwise I think this should definitely go into the upcoming release.

If you have no objections I could also finalize this PR, including the small adjustments required in the CI.

[davegrays]

that would be teriffic @padix-key ! yes please make the adjustments as needed

FYI I went ahead and made the changes you suggested but the install readme could probably be amended further for clarity

[davegrays]

@padix-key btw, any idea when you might want to cut a new release?

[padix-key]

I plan the next release before the end of the year, maybe already this weekend 😃 .
