ui_enable_heaac was ignored and FFmpeg applied Parametric Stereo, so an
HE-AAC v2 stream decoded to 48 kHz stereo whatever the flag: 2048
samples in 2 channels per frame, and ERROR_INVALID_PCM_SIZE for a PCM
buffer sized for the console's output. The console returns the 24 kHz
mono core with HE-AAC disabled, and SBR output at 48 kHz in one channel
with it enabled.
AAC access units now reach FFmpeg without their ADTS header, with an
AudioSpecificConfig built from the header or from the raw parameters.
With HE-AAC disabled it signals SBR as absent. With HE-AAC enabled SBR
stays implicit, and a mono stream that FFmpeg decodes to two channels
is reopened with SBR present and Parametric Stereo absent. The new test
decodes fdk-aac HE-AAC v2 and HE-AAC stereo streams, ADTS and raw, with
HE-AAC on and off; it aborts on main.

All six exports are implemented: MP3 and AAC (ADTS or raw blocks) are
decoded with the bundled FFmpeg and ATRAC9 with LibAtrac9, one unit per
call, into interleaved S16 or float PCM, with the libSceAudiodec
validation and error codes. libSceAudiodec.native is built from the same
sources.
