Helper function for SSObject, test improvements

[astronomerritt]

Fixes #77.

The filter-dependent values on SSObject can now be very easily retrieved in exactly the same manner as filter-specific observations:

test_planetoid.SSObject_in_filter("r").H

You may note I have done this in a rather involved way: I have created a new dataclass just to store these values (FilterDependentSSO) and now SSObject stores a list of these, one per filter. This was to maintain consistency on the user end: observations_in_filter() and SSObject_in_filter() both return objects, which thus have their values accessed in exactly the same way. It's also consistent with how AdlerPlanetoid stores the Observations objects.

Also:

• Unit test for new functionSSObject_in_filter()
• Improved unit test for observations_in_filter() and AdlerPlanetoid.construct_from_SQL()
• Fixed other unit tests to reflect slightly changed behaviour re: SSObject
• Added some no-cover statements to lines which cannot be tested
• Removed the dummy science function
• Altered readme to reflect above removal
• Banned adler.py from code coverage reports

Review Checklist for Source Code Changes

• Does pip install still work?
• Have you written a unit test for any new functions?
• Do all the units tests run successfully?
• Does adler run successfully on a test set of input files/databases?
• Have you used black on the files you have updated to confirm python programming style guide enforcement?

I have tested this and it looks great. I appreciate you getting it working very similar to the other functions! My commit has updated the example notebook to use this (and also to roll loading data from local file/RSP into one nb)

Awesome, thanks!
