No inflate is passed, and that is a property of the format rather than an omission — a
.usdz must store its entries uncompressed so they can be memory mapped, so an archive
that deflates them is not a conforming .usdz and zip.ts says so by number.
A .usdc inside is refused rather than attempted. The binary crate format is specified
and is a separate reader; half-reading it would be exactly the partial import tier 1
forbids.
