[Feature Request] Save File replacement Command Line Argument

[JadeJuno]

(I'm sorry of this issue isn't formatted well, I was expecting a Feature Request template so I'm making up stuff on the spot instead-)

So, I feel like it'd be useful to have a way to open a different save file when opening MelonDS through command line, similar to how you can do that inside the emulator through File > Import savefile. Something like melonds.exe --save-file path/to/savefile.sav path/to/rom.nds

Not sure if this is a good or even plausible idea. I tried making a simple version myself, but C++ kills me so I can't really do much :/
