Add support for User Selection of available games

[Jacqueb-1337]

Fixed with PR #134. Just waiting on an approval to merge with main branch :D

Edit: sorry I forgot to explain myself lol. I forked the project and modified it to allow for user selection of available games instead of just automatically extracting saves of all games on the system.
Also, I would like to coordinate with the devs of this project about possibly assisting with reverse engineering to possibly re-compile previously extracted saves and put them back into the saves folder; for example, if you wanted to transfer a save from one xbox account to another xbox account.
