(dev branch) N163's pitch slide speed is slower in NSF export compared to Famitracker playback

[brickblock369]

I was using the app-emu-module-nsf_driver-dev branch (specifically this version) and I found out that N163 pitch slide speed is slower in NSF export than the playback in Dn-Famitracker.

I tested it by adjusting the amount of N163 channels, but they all are relatively slower in the NSF export.
