wai-rs scene_map (feature scene_map): a bundle (a WWLD world, a WSCN audio
scene, timed media items by content hash) exported as a glTF 2.0 document
with MPEG_media, MPEG_buffer_circular, MPEG_accessor_timed,
MPEG_audio_spatial and MPEG_texture_video, and as a USDA layer of the USD
Core Specification v1.0.1 (prims, translate ops, time samples, asset
references by urn:wai:asset), each carrying the bundle's bytes exactly;
imports read a WAI-written document back to the same bundle (refused
unless re-exporting gives the same bytes) and a foreign one to new WAI
bytes, refused where a value would not carry exactly. Corpus generator
wai_scene_vectors and tests/scene_map.rs.
