Sample databases support for VGM files

[Wohlstand]

Hello!

For a while, this VGM player has a lack of sample database support feature which is used by various VGM files, mainly, crafted through Deflemask or other converters. Why not implement this support also?

I included the example file sent to me by my buddy here.

I would get a shot a bit later, once I get some moment. I am fine if somebody implements this before me.
