just converts framenumbers to split parts for now

mkvmerge-audiocut.py

#!/usr/bin/env python3

"""
Just very basic for now. It only prints an mkvmerge command.
TODOs: 
- properly get input file (or get it at all, lul)
- do the splitting for the user
- actually parse vs scripts
- get delay from source file (and --sync the output)
- add pluses automatically so you only get one file
- generally not be a lazy fuck
