4313917 kept parse_v1_messages out of line (#[inline(never)]) so the
generic parser would not carry the loop; since ef428d7 the slice path is
compiled once in this crate, and the call itself was the remaining cost
of the chunk queue: A/B builds of object_header_parse_x401 with only this
attribute changed put #[inline(never)] and no attribute at 24.5-24.9 us
and #[inline] at 23.6-24.0 us, with 8f59b2e at 23.6-24.1 us. Lazily
creating the chunk list only when a continuation is found (tried too)
measured no faster and was not kept.
Same code otherwise: every chunk-queue check (65,536 chunks, cycles, file
size budget, one chunk buffer at a time, libhdf5 order, overlap allowed)
is unchanged.
