Now uses a customized bootstrap that looks something like Jellyfin. Some
small ui changes were needed. This be overridden by downloading bs5's css and using the custom_css
option if you don't like it. sass file is included for your own modification. Changes made to master have been added also.
Added option email/no_username to disable username input on form, and
instead use the provided email address as the username. Also added
missing 'packaging' dep from pevious update.
setup.py has been removed, and Poetry is now used to package for
install. This fixed an issue i had with uploading to PyPI, so one can
now run 'pip install jellyfin-accounts' to install.
