Fixed HOverRT in python wrapper

[Fratorhe]

Hi,

I realized of an error in the python wrapper where the function speciesHOverRT was actually calling the M++ method speciesCpOverR instead. I added that function with at the reference temperature and the overloaded with H(T).
I fixed this and added a test for it.
I also added a couple of convenience functions (convert_xe_to_ye and convert_ye_to_xe) that were not in the wrapper yet.
The tests for these two functions are only for "existence" verification with dummy inputs.

Best,
Fran

Looking at why this failed on a piece of code you didn't touch, and only for Mac build. The CI/CD for GitHub recently updated MacOS from 12.7.3 to 14.4.1. This also updated AppleClang from 14.0 to 15.0. Without seeing the actual failure log, I would guess this OS/Compiler change shifts the numerics just enough to trigger failure. Presumably master branch would also fail if we re-ran the testing now.

If I could see the test log for the Mac build (or if I had a Mac), I could see which check needs a little more wiggle room; but unfortunately I can't.

Yes, indeed, I also found it weird that it failed for MacOS. I am on Linux and I do not have access to any MacOS machine...

I am adding some other functions to the python wrapper and I will include these.
