ym2413+ay8910 to ym2608, PSG detuning occurs
I first converted ym2413+ay8910 to ym2413+ym2608.ssg, and then converted it to ym2608.fm+ym2608.ssg. At this time, I found that ssg was two tones lower. If I convert ay8910 to ym2608.ssg first, and then convert ym2413 to ym2608.fm, it will cause the rhythm drum sound to be completely invalid and ym2608.fm is two notes lower than ssg.
vgm-conv -f ay8910 -t ym2608 -i in.vgm -o temp.vgm

It is currently confirmed that 0.8.0 does not have this problem, but the latest 0.10.0 has this problem.
