Out of Place GEOS ATS

[cssherman]

This PR does the following:

1. Uses a separate test directory (the location of the ats files), working directory (location where the tests are run), and baseline directory.
2. Uses the test directory structure for the working and baseline directories
3. Removes a bunch of unused/broken code in TestCase
4. Removes unused report types
5. Re-works the report base class to use modern ATS approach (removing a bunch of unnecessary/broken manual checks)
6. Replaces manual html table construction with the tabulate package
7. Updates the style/format of the html documentation

I'm going to work on branches of GEOS/integratedTests that implement this version next

So much code removed!
This would require testing of course. Is it OK on the CI?

Absolutely, and I'm sure there is more. I ended up using this package to help identify unused code: https://pypi.org/project/vulture/

Maybe use parser.add_argument(...., choices=action_options.keys(), ...) which would make the check and the doc +/- automatic? Same for check_options and verbose_options but I cannot find those in the parser 🤣

Is sys.argv = atsargv even legal?? 😲

[cssherman]

This was actually one of the less weird things that our original version of ats did... We're essentially intercepting the command line args, doing some custom work, then creating new args for ats.

[TotoGaz]

Do you have to do this chdir? I've seen that was done like that in the previous code, but it sucks so much!

[cssherman]

I think that I've changed enough of the code to use absolute paths at this point... I'll give this a shot

great!
