Overhaul RMG-RMS Python-Julia dependencies

@mjohnson541 pointed out that this will likely break RMG's CI. Could you point out where in RMG CI do we need to change to avoid breaking it? cc @JacksonBurns

@mjohnson541 Recording our offline discussion here: We should replace pyjulia with JuliaCall in RMG (see here: https://juliapy.github.io/PythonCall.jl/stable/pycall/). It should make the installation process easier. cc @JacksonBurns

@hwpang you can open a pull request against RMG-Py and change this line of the CI file (https://github.com/ReactionMechanismGenerator/RMG-Py/blob/eed950a389738e70894c25e1d8388bb20ef75947/.github/workflows/CI.yml#L155) to install this branch of RMS from your repository. We can then just see the failures live.

RMS-RMG twin PR: https://github.com/ReactionMechanismGenerator/RMG-Py/pull/2640

[mjohnson541]

I've done some verification on the juliacall end:

1. The primary trick I used to make pyrms from pyjulia works with juliacall
2. I think we can get around the need for diffeqpy, at least I think I circumvented our original reason for needing it...which should be nice because pyrms will no longer need the full DifferentialEquations.jl installed.

I think in terms of merge order this would look like: merge the RMS PR, merge a pyrms PR, build new binaries for pyrms, and then merge RMG PR.

@mjohnson541 Can you make the pyrms PR since you've looked into this? Thanks

@mjohnson541 Can you make the pyrms PR since you've looked into this? Thanks

Yes, I'm waiting until this PR is building properly, right now I wouldn't be able to test the pyrms PR properly.

@mjohnson541 I addressed your comment and had a question. I will write pretty commit messages after we agree on the changes

[hwpang]

Removing the duplicate export would cause the test to fail. I undo the change.

@mjohnson541 This is ready for another review / approve. Need to clean up the commits after approval and coordinate to merge at the same time with https://github.com/ReactionMechanismGenerator/RMG-Py/pull/2640.
