Make it so we can get the latest release automatically without having to keep updating it by hand (#141)

* Initial work on auto increment pyscript versions

* Make sure to ignore exceptions if we cant connect to internet

* Revert change to version

* Actually make it so it's v0 to follow PSDC

* types because mypy wants them
