Bump the version of njs

Bump the version of epson-escpr

I’ve been these two on my config for a year with no issues:

an initialHashedPasswordFile option, using agenix to handle the password is currently not possible without exposing the contents to the nix store using builtins.readFile

Relatively complex module, may need more effort to review than usual.

A new python package, useful for interfacing with fedora packages in the context of Nix.

^ A python GUI package. Large diff due to several dependencies needing to be added.

^ standard unfree package

Fixes up some errors/wording in the existing password option documentation and adds tests to demonstrate the true behavior. More eyes on the new content/wording would be good.
