added loading icon to android
will check `Data/Sprites/Android/Loading.bin` and then `Data/Sprites/UI/WaitSpinner.bin`
fades in and out, renders outside of game
revamped launcher:
- custom path done, will prompt path on first launch and will reconfirm after if needed
- creates .nomedia file like it meant to all those months ago
revamped java-c interface
- file descriptor access now passed to c by java
- logging now one pretty much entirely javaside, gives a HUGE speedboost
tested working on android 10 and android 11 (apis 29 and 31 (32?))
