Make NuGet package workflow

[Exouxas]

I haven't looked enough into this, but I would like there to be a workflow that automatically makes a NuGet package of this library whenever there's a new version. Maybe with automatic versioning?

I'll have to research how others do it to see what is common.

I'm considering keeping this fully manual to ensure it won't have code-breaking issues.
