Good to know

virtualship now comes with a virtualship.static folder which is used to store static files (e.g., example configuration .yml files). For data files (which are larger, and aren't as core to the functionality of virtualship) shouldn't be put here but instead should be downloaded on demand.

virtualship.utils contains a bunch of utilities for virtualship, including convenience functions for reading these static files

Static files aren't being packaged properly despite working locally. Removing the --no-build-isolation flag would fix it, but I'm not 100% sure if that's the right fix. Waiting on reponse in https://github.com/pypa/setuptools/discussions/4694

[VeckoTheGecko]

Decided to just remove the flag --no-build-isolation
