Ecape-parcel

Fixed a fatal crash that would occur upon importing ecape_parcel.

The package now uses Equation 24 from [Peters et. al. 2022](https://journals.ametsoc.org/view/journals/atsc/79/3/JAS-D-21-0118.1.xml) instead of Equation 8 from [Peters et. al. 2023](https://arxiv.org/pdf/2301.04712.pdf).

Now has four different types of ascent:

* Pseudoadiabatic Non-Entraining (currently the conventional method)
* Pseudoadiabatic Entraining
* True Adiabatic Non-Entraining
* True Adiabatic Entraining

Installation instructions in README.md

The package now uses Equation 24 from [Peters et. al. 2022](https://journals.ametsoc.org/view/journals/atsc/79/3/JAS-D-21-0118.1.xml) instead of Equation 8 from [Peters et. al. 2023](https://arxiv.org/pdf/2301.04712.pdf).

True adiabatic non-entraining parcels have now been verified to work correctly. Work is ongoing on ensuring entrainment and pseudoadiabatic ascent behave correctly.

!! This code has not yet been run through any verification datasets. I am currently working with the author of the paper to verify that this works properly. !!

To use the library, it is recommended that you install through PyPI (<a href = "https://pypi.org/project/ecape-parcel/">ecape-parcel-py on PyPI</a>)

`pip install ecape-parcel`

Attached to this release is the source code for the project. Future changes are expected to be limited to bug fixes.
