Description
Indices into the vectors in HeaderMap are guaranteed to fit within u16 (see #386), but the header::map::{Link, Links} types store them as usize.
Changing these fields from usize to u16 would reduce memory footprint and might improve cache-friendliness of HeaderMap.

Research direction
Locate the HeaderMap implementation and the header::map::{Link, Links} types mentioned in the issue, then inspect how their indices are stored and used. Check the constraints established by #386 and existing tests or benchmarks for HeaderMap; done means the indices use u16 consistently without breaking behavior or bounds assumptions.
