New scriptmodule for Master System & Game Gear emulator

SMSPlus-GX:
https://github.com/libretro/smsplus-gx

Advantages over the current ones in RetroPie:

• Properly detects games with FM (YM2413) music, playing it without configuring anything.
• Runs japanese games (today, only Picodrive does it consistently).
• Runs games that glitch out in other cores, i.e. World Grand Prix.

Create the file ~/RetroPie-Setup/scriptmodules/libretrocores/lr-smsplus-gx.sh with the following content:

#!/usr/bin/env bash

Then, run RetroPie setup, go to experimental packages and you should find lr-smsplus-gx.
It's my new default emu for SMS, and should be included officially in RetroPie IMHO.

You could create a pull request to get it included officially in RetroPie

@quicksilver I kinda have a track record of "ignored PRs" spanning a number of projects, so I'm not a fan of doing them anymore.
I'd rather have the changes visible for those who need the new features; easier than having them in Github and make people look for them.

Seeing that I've created a second scriptmodule for another Sega 8 bit core, this time I've opted to do a PR for both:
https://github.com/RetroPie/RetroPie-Setup/pull/3170
I hope this one has a future.

Just in case, Gearsystem, the new core, is not better than SMSPlus-GX, but has SG-1000 support.

SMSPlus-GX looks interesting. Thank you for submitting a PR and keep submitting them and don't be discouraged! 😊
