live reloading was intended for previous release, but needed some
tweaking. Settings that still require a restart are marked with an R.
Fixed issue where default values weren't being filled in on reload of
config that broke emails if settings were changed at all.
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.
