- Includes major improvements by Drexel for refactoring the `CalcCN` and
associated functions to reduce computation time. Accomplished by extracting
code to a number of independent functions, vectorizing, and memoizing them.
This results in an average speedup of 75% overall.
- **BREAKING** `parser` has been renamed to `Parser`
- **BREAKING** `run` now returns a tuple instead of a single value. The first
value is a JSON of results, same as before. The second value is the internal
model `z` which could be used to modularize the GMS writing in the future, as
the JSON conversion currently done is lossy.
- `numba` is now a dependency, and must be installed prior to installing
`gwlf-e`
