Dylan M. TaylorandRene Leonhardt 392b8720cd craft-psd: less copying and compression work when encoding planes (#1043) ...

- PackBits scans each row once; RLE planes encode their rows on worker
  threads on native targets (rayon), keeping the exact packet boundaries
  and the fallback when RLE does not pay.
- ZIP output grows in bounded blocks and is compacted to its encoded size,
  instead of reserving the raw size; native threads reuse a finished
  encoder's working buffers.
- 16/32-bit prediction works on owned buffers in one pass.
- Filter-effects planes and pattern blocks encode from borrowed rows and
  owned buffers without the intermediate copies.

The encoded bytes are unchanged.

Ported from storytold/photocraft#7797 (its crates/psd part), at
