fix(rockbox-codecs): route raw ADTS "aac" streams to aac_bsf, not the MP4 codec
`afmt_for_ext("aac")` mapped raw ADTS/HE-AAC streams (content-type
audio/aac / audio/aacp) to AFMT_MP4_AAC, whose libm4a demuxer needs
moov/mdat atoms and fails outright on a raw ADTS frame stream — HE-AAC
internet radio played silence. Map "aac" to AFMT_AAC_BSF (the bitstream
decoder), matching Rockbox's own get_afmt_from_content_type() and the
.aac file-extension table. .m4a/.mp4 keep AFMT_MP4_AAC (they use the
seekable/file route, not forward streaming).
Verified: the alt64 aacPlus stream now decodes at 44100 Hz (SBR active).
Bump the affected crate chain (patch): rockbox-codecs 0.2.1,
rockbox-playback 0.4.1, rockbox-ffi 0.3.1, and rockbox-wasm 0.1.2
(ships the recompiled core).
