[REQ] Option to choose location of .prism folder

[0xlne]

The /sdcard space is easily spammed with apps using it as storage space for simple things like settings. As a user I like a clean & minimalist sdcard space & thus request an option to choose the location of the .prism folder; example: /sdcard, the app data folder in /data/data, /sdcard/Android/data/, or allow the user to choose a location with SAF.
