scripts: add dir

Add 2 scripts that I just used, could be useful.

scripts/kf4-group-sounds.py

+"""Group KF4 sound files together in named dirs for later use w/ mkpsf2.
+
+Some tools to handle sounds have issues with PS2 sounds split as HD/BD/SQ, so
+grouping them with this script makes it easier to batch process them with mkspf2
+so you can process them later as PSF2.
+
+Example:
+
+```bash
+$ ./kf4-group-sounds.py workspace/dat/snd/ workspace/soundgroups
+$ cd workspace/soundgroups
+$ ls -lF
+bgm000/
+bgm001/
+...
+$ fd -t d -x wine mkpsf2 {}.psf2 {}
+```
