Rename files inside selected folders.

This script allows the user to select multiple folders and then renames all the files inside these folders. Both the PySimpleGUI FolderBrowse() and popup_get_folder() only allow a single folder to be selected so this script is an example of how to select multiple folders.

The renaming is specific to my use but is done in rename_files() and can be changed for different needs. My renaming uses the parent folder name as a base then adds a number as a suffix which is incremented for each file in the folder.
