mednafen: Update to 1.24.3

-- 1.24.3: --

May 1, 2020:
	SS: Implemented more complete emulation of the SCSP short waveform mode, after \ 
running further tests; fixes excessive distortion in a
	sound effect in "Sega Ages: OutRun", a regression introduced in \ 
Mednafen 1.24.2.

April 25, 2020:
	Fixed broken support for systems without any usable OpenGL implementation available.

April 24, 2020:
	Apple2:  Adjust disk angle variable upon disk change, partially sanitize the \ 
disk angle variable on state load, and print out a debug error
	message instead of triggering an assert() in the disk reading code, to prevent \ 
Mednafen from aborting out in certain circumstances involving disk
	changing and state loading.

April 21, 2020:
	Apple2: Added missing keyboard reading variable to save states.
