mednafen: update to 1.22.2.

-- 1.22.2: --

April 23, 2019:
	PSX: Fixed a regression introduced in 1.22.0-UNSTABLE that broke a few PS1 \ 
games(e.g. SimCity 2000 and Rise 2).

	Fixed issues with inline functions in the QuickLZ code that could cause linker \ 
errors when compiling with optimizations disabled.

April 14, 2019:
	Apple2: Added basic WOZ 2.0 disk image support.

April 13, 2019:
	NGP: Fixed a sequence point rule violation that could cause "Gals' \ 
Fighters" to malfunction when Mednafen was compiled with clang,
	per tip from stellarporter.

	SS: Added the European release of "Theme Park" to the internal \ 
database of games to use the data cache read bypass kludge with,
	to fix a crash/hang during the intro FMV.

	Lynx: Fixed an old heap buffer overflow bug that could be triggered if the \ 
emulated game set up registers and RAM in a
	certain way.

March 18, 2019:
	PCE: Fixed an old bug(looks like from around a decade ago) in the HES playback \ 
code; it caused periodic high IRQ latency,
	which resulted in timer IRQ-driven DDA playback sounding rougher than it should \ 
have.
