Weapon fire (and ~all one-shots) played FOREVER: sf2extract flagged a sample as
looping whenever the SF2 shdr had loop points -- but almost every SoundFont sample
has loop points; whether to actually loop is the instrument's sampleModes generator
(igen oper 54): 0/2 = one-shot, 1 = loop, 3 = loop-until-release. The old heuristic
looped 239/241 samples, so SetupPatch set AL_LOOPING=1 on fire/explosion/step sounds.
Read sampleModes at the same igen zone as sampleID and loop only on 1/3. Now
166 one-shot / 75 loop: LaserAFire/BigExplosion/BasicClick -> ForceStatic (one-shot),
EnginePower/EngineMotor/coolant -> LoopAtWill (correctly sustained). Regenerated
audiopresets.cpp; the WAV PCM is unchanged.
