v0.3.1

What's Changed

• Fixes a nesting issue & adds integration tests by @neil-morrison44 in #3

• nested folders with the -f option were previously a little too nested, now common/game_name/game_name.cue -> /game_name.json & common/nested/game_name/game_name.cue -> /nested/game_name.json as I intended
• also fixes a potential issue with the data_path when used on windows (\ instead of /)
