Finish photometry notebooks

[mwcraig]

This pull requests finishes off the notebooks needed to perform photometry in 2.0.

Still to do:

• [x] Ensure coverage on new code is 100%
• [ ] Add new notebooks to launcher
• [ ] Check for an intermittent error when starting notebooks from the launcher. Some times jupyter lab gets very confused and can't display widgets. Hoping this was just a one-time thing.

NOTE:

• do not review this yet; currently it is unfinished and contains all of the changes in #371

• 371 should get merged before this.

@JuanCab -- this is ready for a look. Sorry it got a little long. Once this is merged it will be possible to perform photometry via notebooks.

I'll work on a separate PR to add some more documentation and another to make the command line approach is fairly straightforward.

I'm not sure why coverage thinks we need to test our test files....
