[Feature Request] Allow for the use of multiple romfs folders

[piplup55]

right now you can only use one version
example if you have multiple dumps like 1.1.0 and 1.2.1, you can only use one
the solution would be to scan the folder for version names in the folder name selected or some form of naming schema and add them to a drop down below the path box (it doesn't have to be below the path box it's just what i would recommand to not confuse people)
the folder layout may look like this

To avoid difficulty with the folder structure, you will just be able to add multiple paths individually and they will be parsed for their version, similar to the export locations.
