Import/export EEPROM saves from othe emulators

[RetroEdit]

SkyEmu currently uses a byte-order convention for EEPROM saves that matches GBA technical specifications.

However, this makes it slightly inconvenient to handle saves from other common emulators, which follow a different convention that VisualBoyAdvance created. This includes emulators such as mGBA and NanoBoyAdvance, which copied this convention.

There's not really a general way to detect this difference, but it would be nice if SkyEmu had was able to manually import and export these saves. If I recall, mGBA has an option for importing/exporting to the other format.

There's another hack I thought of: you could a file name suffix (_VBA maybe?) in the save file name to indicate the alternate save file format, and automatically load/save those differently, but this probably adds unnecessary complexity.
