game2m3u - Multi-Disc games inside Directories (gdi/bin/raw)

[CygnusHyoga]

Hi! First of all, congratulation for an excellent tool for generate m3u files for multi-disc games!

I have a problem/feature request for improvement of the tool. It'll be nice to add a possibility to convert multi-disc games inside multiple folder, with gdi/bin+raw, for example (dreamcast games):

Problem

Directories:
Shenmue II v1.003 (2001)(Sega)(NTSC)(JP)(Disc 1 of 4)[!]
Shenmue II v1.003 (2001)(Sega)(NTSC)(JP)(Disc 2 of 4)[!]
Shenmue II v1.003 (2001)(Sega)(NTSC)(JP)(Disc 3 of 4)[!]
Shenmue II v1.003 (2001)(Sega)(NTSC)(JP)(Disc 4 of 4)[!]

Files in each directory:
Shenmue II v1.003 (2001)(Sega)(NTSC)(JP)(Disc 1 of 4)[!]\
Shenmue II v1.003 (2001)(Sega)(NTSC)(JP)(Disc 1 of 4)[!].gdi

track03.bin
track04.raw
track05.raw
track06.bin

track06.bin

Posible solution

I think a good approach , will be to create a subfolder inside without renaming the tracks (bin/raw/etc.):

METHOD A - Create subfolders without renaming tracks
