[libretro] Gyro very sensitive—Option to adjust gyro sensitivty?

[nijoakim]

I was just playing WarioWare: Twisted! on RetroArch on a Samsung Galaxy Flip 3 and noticed that gyro is much more sensitive than in the original game. I don't know whether the gyro sensitivity differs much between phones or whether the mGBA core is always too sensitive, but in either case, I figured it may be a good idea to add a core option for adjusting the gyro sensitivty.

If you want to experiment to get it right, you can play Dr Crygor's minigames as they are gravity-based, and thus for some of them it is easy to figure out what is down and thus also figure out the correct sensitivity. I uploaded a save file for Wario Ware: Twisted with Dr Crygor unlocked here: http://nijoakim.com/wwt.srm.

I played WarioWare: Twisted on RetroArch on an Ayn Odin 2 and confirm it is way too sensitive. +1 for sensitivity settings!
