[Suggestion] Allow selecting a windows library in when opening/creating TagStudio library

[NiXTheDev]

For Example if there are multiple users, they might have TagStudio installed for all of the users, or some may have opted out, but they still would want to access the files in the library in an organized way

Also an option: automatically create windows library for TagStudio that includes the folders of the main libraries(i.e. music, documents, photos and etc.)

[Loran425]

The ability for multiple libraries is planned for down the line.

A macro to add default windows libraries could be an interesting idea once a user defined macro method is added
