Pending multi-byte context for the byte-at-a-time decoder (see `decodeUTF8`).
`Ready` is a codepoint boundary; the others hold the lead byte and the
continuation bytes collected so far while more are awaited. `ThreeA`/`FourA`
also carry the lead's byte offset, the only states whose error (overlong /
surrogate / out-of-range) is reported AT the lead rather than at the byte
being read.
