The audio-path calculation, the export progress and thumbnail calls and
the four metadata calls are valid calls the libraries don't answer yet.
Checks requiring them to throw would fail as soon as one is
implemented, so the exact NotImplemented checks and their helpers go,
along with the output checks that depended on those calls. The
NotImplemented_nid_no_patch conversions, the debt entries and the
argument, session and handle checks stay.
Asked for in oneandonlydean's review.
After its handle and argument errors, sceAudioPropagationSourceCalculateAudioPaths threw a bare runtime_error for every valid call, so progress.py counted it as done. Propagation is not implemented, so the valid call now goes through NotImplemented_nid_no_patch. The early errors are unchanged.
sceAudioPropagationSourceRender accepted only format 2. The RenderInfo
word at +0x28 is SharpProspero's AudioPropagationOutputFormat: 0, 1 and 2
are first- to third-order Ambisonics (4, 9 and 16 float channels), 4 and 5
are 8 interleaved float channels. SAROS (PPSA07631) renders format 0.
Other values still throw, and an output that is not a whole number of
frames is rejected. Based on db91769497 from the JJenkx fork.

The nine Init helpers are static inline in the SDK header and the bare sceAudioPropagationSystem name is in neither the header nor the stub, so the library no longer exports them.

sceAudioPropagationSourceRender takes the system, an array of RenderInfo
descriptors and their count: PPSA21564 and PPSA21567 pass one RenderInfo
{0x010107d6, 0x30} per call, with the source handle at +0x10, its output
buffer at +0x18, the buffer size in bytes at +0x20 and the word 2 at
+0x28, once per audio grain for each propagated source.
Without acoustic propagation a source contributes nothing, so each
output buffer is zeroed for its size. Every RenderInfo is checked first
(descriptor, a live source of this system, a non-empty output), and a
count of 0 or a format word other than 2 throws, as neither has been
observed.
The 22 exports used by PPSA21567 take the call shapes recovered from its
call sites (#481): destroys take the system and the object, attribute
setters take a count, SourceCreate takes only an output handle,
UnregisterMaterial only the material.
The system lives in the title's CPU memory (16-byte header, no GPU memory)
and its handle is that address; rooms, portals, sources and materials are
counter handles. Attributes are validated and have no effect; no rays are
requested and sources report no audio paths. Non-empty ray results, path
calculation and audio paths throw, SourceRender stays unimplemented, and
invalid input throws because no error code is known. Objects left when
their system is destroyed become unusable; their later destroy or
unregister is a no-op.
