[Request] Add region & language params for automatic renaming of PSP games

[generic-rocker]

When obtaining a PSP game from NPS Browser, pkg2zip automatically names the file with the naming convention of "Title [Game ID].iso", while using the default params (-x {pkgFile} "{zRifKey}").

This is a request to add a param for the region. Ideally I'd like to have it automatically name the PSP games with a naming convention of "Title (Region) [Game ID].iso".

A param for language(s) may also be helpful.

Thanks in advance!
