GetFloorPosition_FG and GetFloorPosition_BG were outrageously bad names
given that they are also used for finding walls and ceilings.

zFinishTrackUpdate actually clears variables relating to modulation
envelopes.

They now need to be matched in pairs.

accurate-kosinski is more accurate, clownlzss is faster, and they're
both now more portable.

I've tested that produced ROMs are still accurate and functional.

Since I'm an Arch Linux user, it would normally be a bad idea for me
to share binaries since they might expect a newer glibc than other
distros provide.

To work around this, I've compiled s3p2bin statically using the musl
C standard library. This produces a more-portable binary that does
not rely on a particular version of glibc.

Was this an accidental inclusion?

Yes, I was debugging the generated command line to make sure that the
path given to -i was valid, and forgot to remove it after.

This parallels the documentation of this code in my 'Knuckles in
Sonic 2' disassembly. Between the two version, there are the
following differences:

* KiS2 changes Knuckles' radius multiple extra times.
* S3K has code for reverse-gravity mode.
* S3K has an extra block of code for detaching Knuckles from walls if
  if the floor is directly under him even when he isn't moving, which
  introduces a bug where Knuckles' climbing animation always resets
  to the first frame when he isn't moving up or down.
