Fix introspection and apply formatting fixes

[watzon]

Closes #45

[watzon]

Looks like it's just failing because of Ameba issues that were there before I made any changes

[jgillich]

Looks good, thanks. The Ameba problems seem to be fixed in the master version, if you don't mind, could you try adding branch: master to the shard.yml?

[watzon]

@jgillich you mean the master branch for ameba?

[jgillich]

Yes.

[watzon]

Doesn't seem to fix the problems for me since most are not_nil! issues, but I'll do it and push anyway

[jgillich]

I'd do it myself but my devcontainer doesn't want to start right now and I'm not sure why 🤔

[watzon]

Looks like we're good!

[jgillich]

Thanks
