Update to v095 release.

byuu says:

After 20 months of development, higan v095 is released at long last!

The most notable feature is vastly improved Game Boy Advance emulation.
With many thanks to endrift, Cydrak, Jonas Quinn and jchadwick, this
release contains substantially improved CPU timings and many bugfixes.
Being one of only two GBA emulators to offer ROM prefetch emulation,
higan is very near mGBA in terms of accuracy, and far ahead of all
others. As a result of these fixes, compatibility is also much higher
than in v094.

There are also several improvements to SNES emulation. Most
significantly is support for mid-scanline changes to the background mode
in the accuracy profile.

Due to substantial changes to the user interface library used by higan,
this release features yet again a brand-new UI. With the exception of
video shaders and NSS DIP switch selection, it is at feature-parity with
the previous UI. It also offers some new features that v094 lacked.

The cheat code database has also been updated to the latest version by
mightymo.
