Fixed 8xx effect for MODs, which have a range of 00...FF, not 00...7F or 80 or whatever
Added documentation from the original project
Moved internal headers out of public dumb.h
Fixed IT envelope loop pickup when the loop start is not on the first tick
Removed start of note ramp when raising volume from zero on a running note, as normal volume ramping will already kick in

Reworked declicker final volume propagation a bit
Envelopes do not carry when New Note Action is Cut
Fixed compilation errors/warnings
Renamed init_cubic function in preparation to make it public
Implemented automatic detection of SSE support
Made resampler and SSE filter setup functions public, in case anyone wants to call them early to prevent possible but harmless race conditions
Copied LONG_LONG definition inside of tarray header so it doesn't need to include the main dumb header
Fixed a C11 warning by adding a macro lock around blip_t declaration
Fixed Asylum Music Format panning effect
Simplified pan law calculation a bit
Fixed IT mixing Dxx regular volume slide with cx/dx volume column slide effect
