FF8: Fix battle stage texture dump + option to use music files from remastered

[myst6re]

Summary

Fix battle stage texture dump with save_textures on.

option to use music files from remastered => if you extract the ogg files from remastered archives, you obtain files named like:

• 008s-antena.ogg
• 018s-julia.ogg
  It is the same format as the original game, but the extension is replaced from sgt to ogg. Also this does not use xg files naming

Motivation

I expected at first that Roses and Wine mod was using the same file name pattern than the original game.
That's not the case, we need to maintain a list of filename, that I don't want to.

But as a quickwin I can add the option for users who want to import oggs files from the remastered version to the 2013 version.

ACKs

• I have updated the Changelog.md file
• N/A I did test my code on FF7
• I did test my code on FF8
