NeoGeo Sound Fixes (Patreon)

I have spent a few hours today fixing sound problems in the NeoGeo core. Thanks to loloC2C for showing specific examples of broken sounds so I could debug it.

Sorgelig will eventually update the repository and publish the changes but if you want to catch up with the latest RBF; I am posting it in my Discord channel, here. I do not consider this a beta release or any release at all. These are work builds that just sound much better than the latest release.

Some of these bugs also affected the CAPCOM cores, so I will be releasing a major update of sound+128 MB support soon. GunSmoke pause screen is ready too, so public release will happen soon too.
