Add a shop generator

[Rinzii]

As a DM, I want to be able to generate shops so that I am able to create a shop on the fly and have it for reference to use later.

This may be a bit difficult to make something robust and useable without beinghyperspecialized.I will have to also look further into this topic as there will be some specifies that will need to be done but overall, not too terrible.

But for the time being this is something that's gonna more so be on the back burner till more internal utilities are created.
