Khawar Zamman WaniandClaude Opus 5.5 4001a3092a TIFF: open images over 2^30 px, decoded a group of rows at a time into the layer (#8169) ...

The 117,504 x 22,464 px banner from #8456 failed with "2639609856 pixels
exceed max 1073741824": the decoder built the whole image in one buffer
and the importer copied it into tiles, so the decode was capped at 2^30 px.

- codecs: decode_ifd split into prepare + decode; new TiffBands decodes
  ~64 MiB groups of bands in parallel and hands each group, upright, to
  the caller. Limits::banded(): 300,000 px a side on 64-bit, max_alloc per
  group; 32-bit targets keep the whole-image check.
- raster: Surface::try_write_interleaved (fallible, tiles on all cores).
- io: import_tiff_page decodes flat pages through TiffBands straight into
  the layer, converting pieces of rows on all cores; layered TIFFs keep
  the whole-image path.

Release, 20 threads: 36 MP 220 -> 52 ms; 30,000^2 6.8 s / 6.43 GB peak ->
1.1 s / 3.86 GB; 35,000^2 and the 2.64 GP banner now open (1.5 s, 3.3 s).
