Updates installer issues and resolves the pyomo logging error

[samgdotson]

This PR resolves several issues.

1. Closes New Pyomo version bug? #50 -- For some reason, either the pyomo or logging libraries ignores the logging.setLevel function. I resolved this by following the solution from this stackoverflow.
2. This PR updates package installation by retiring the setup.py file and adding a pyproject.toml file. The recent NumPy update to 2.0 caused some dependency issues with Pyomo. These issues have apparently been resolved in version 6.8.0 of pyomo. Since the current build works I have not pinned any versions.
   • Closes Failed pip install #55
   • Closes Numpy 2.0 breaks osier #59
   • Closes Running tests yields error of cbc solver #60
3. Closes Failed tests on Windows (10) #56 by adding windows and macos to the CI build. Along with several versions of Python (3.9-3.12).

This PR also addresses some comments from @fredshone JOSS review:

• Adding a windows machine to the CI
• Adding a code coverage test -- it does not however add a badge to the readme because this project does not have codecov enabled and the "free" badge solutions seem extremely hacky. I'm also not keen on manually updating a badge icon. Happy to hear suggestions, though.

Note

Contrary to @fredshone's request in #56, I changed the default solver to cbc for the test suite, instead of having GLPK. The Calliope project had a nice example for installing CBC on a windows machine via GitHub CI. I haven't found an equivalent command line only guide to installing GLPK.

Local Checks

• Passing tests (yes, with a single numpy deprecation warning -- from a dependent package).
• Docs build (yes, with a couple of warnings)
• Examples run successfully

This is a great PR Sam. Glad you resolved all the pyomo issues!

Thanks @yardasol! Care to merge?

(Merging was previously blocked by a ruleset waiting for a status update from the "Build and test" job. I'm not entirely sure why it wasn't being triggered, even though all of the checks within that job passed).
