SoundTouch audio processing library — modified by SMPLER

SoundTouch Copyright (c) Olli Parviainen. Licensed under the GNU Lesser General
Public License, version 2.1 (full text: SOUNDTOUCH_LICENSE.txt).

Base: SoundTouch 2.4.1 as imported into SMPLER on 2026-06-17. Two files of that
import (FIFOSampleBuffer.cpp, RateTransposer.cpp) already carried upstream
SoundTouch changes made after the 2.4.1 release; they are not SMPLER changes.

Files modified by SMPLER (2026-10-06):
  - AAFilter.cpp  — the work buffers of the anti-alias filter design live on the
                    stack up to 256 taps (SMPLER uses 64), so a live pitch change
                    allocates no memory. The computation is unchanged.
  - FIRFilter.cpp — the coefficient buffers are reused when the filter length
                    does not change (no new/delete on a live pitch change). The
                    coefficients are written exactly as before.
