QOL: Open a BEAT object directly via `--bid` cli option

Summary

Adds the "--bid" option for opening the editor directly to a BEAT object. A custom click param type tries to resolve the passed string to a BEAT object file path.

I tried to generously parse the given input so the user could just type the object name (see the comments in the new click type for more info).

Relevant issue(s) fixed

I consider this to be part of #186 (closed), but it's really just a QOL feature
