pitch: add validate tests Add pitch tests with different forward and backward playback rates. Those tests depend on the libSoundTouch version to validate the buffers checksums. The actual version uses libSoundTouch 2.3.2, use the `--force-fallback-for=soundtouch` meson option to build using the same version.
