Pandas deprecated lower case d here: pandas-dev/pandas#58998 Upper case d `D` is calendar day: https://pandas.pydata.org/docs/user_guide/timeseries.html#period-aliases
pyarrow provides native string dtype support for mhkit. While technically optional, mhkit benefits from one standardized backend for representing columnar data. At this time pyarrow is that standard.
The narrow hdf5 range causes the solve when pyarrow is included to be slow. Increasing the allowed range improves the pip solver speed.
These should no longer be necessary with the changes to dependencies
This removes any explicit coveralls intalls in favor of the coverallsapp/github-action@v2 which is self contained and contains all binaries necessary for coveralls to run.
Agg is a non interactive matplotlib backend and lets the tests runh
"headless". Without this specification tests can choose their backend
which can sometimes lead to failing tests on headless machines (GH
Actions).
