, nsfplay 2.5 is real and official now!

https://github.com/bbbradsmith/nsfplay/releases/tag/2.5

i'm not sure what has changed from the beta version that was floating around before (which also had the fixed VRC7 emulation), but this one is surely worth updating for! first release in quite some time!

here is the list of updates from the release

------------------------------------------------
APU frequency dividers now count down (more accurate pitch change timing).
Keyboard view speed control setting should reset to normal when the program restarts.
DPCM bit-reverse option.
Playback advance options (auto, infinite play, single track).
Negate sweep init option (compatibility with old SuperNSF, etc. that relies on nonstandard sweep init).
Option to force VRC7 replacement with YM2413 (OPLL).
DPCM read delay adjusted (4 cycles is a more accurate approximation than 2).
Default volume of APU 2 raised to match measured triangle volumes.
Fixed triangle and noise being logically inverted.
Fixed error in track selector length when using NSFe playlists.
Integrated VRC7 (YM2143) emulation update from Mitsutaka Okazaki.
Linear square mix level now matches nonlinear at 1 full square.
Fix winamp playlist generator track titles.
Write protect internal player memory.
