YaruChipFont v2: More In Tune Edition

A small but significant update: I realized why a lot of the SF2 font's samples were sounding out of tune (defaulting to the wrong key in Viena) and they're all corrected to be properly centered around Middle C now. This means using YaruChipFont alongside another soundfont shouldn't sound noticeably disharmonious anymore... hopefully. I'm basically tone-deaf, so I've got a limited ability to assess this situation.

The audio samples themselves are the same, it's just the metadata affecting them in the SF2 file that has been altered.
