sceAjmBatchJobDecodeSingle runs a single-frame decode job with the stream
sideband. sceAjmBatchJobGetGaplessDecode and sceAjmBatchJobGetCodecInfo
append run jobs without buffers that return the gapless-decode and codec-info
sidebands.
A run job without input or output buffers no longer decodes: it reports the
instance state with a zero result instead of PARTIAL_INPUT on MP3 and Opus.
RUN_GET_CODEC_INFO (bit 11) writes the ATRAC9 codec info after the gapless
sideband. Codec info for other codecs, and codec info together with
RUN_MULTIPLE_FRAMES, throw.

Read the MPEG audio frame header and report the frame size, channel
count, samples per channel, bitrate and sample rate. The signature,
the result layout and the rate tables follow shadPS4's reimplementation
of the PS4 library. Requesting the original file length throws: that
lookup is not implemented.

Batch jobs were stored as a 72-byte header plus 16 bytes per buffer, so one decode
job took 104 bytes. GTA V initializes its MP3 batches with 0x40 bytes, every
sceAjmBatchJobDecode returned SCE_AJM_ERROR_OUT_OF_RESOURCES and its streamed
music and speech stayed silent. A job is now a 32-byte record, its buffers, and
its parameters only when it has any; the MP3 test decodes through a 64-byte batch.
