* craft-cms: the changes PhotoCraft made to its copy since extraction

PhotoCraft kept editing crates/cms after craft-cms was extracted from it at
storytold/photocraft@b3222ee8. This ports its 41 commits up to
storytold/photocraft@0143b148 with a three-way merge per file, keeping the
changes craft-cms made on its own (Result-returning API, white preservation,
FOGRA39, named colours, profile ID).

Ported: the .3dl shaper, Mesh header, UTF-16 and .look fixes in lutfile; the
checked ICC offsets and the per-profile curve sample budget; same_bytes and the
byte-confirmed transform cache; the blocked matrix/TRC path and the 8-bit
first-stage table; GpuMatrixShaper; cicp_rgb; the ACEScg and Dot Gain 20 %
built-ins (the latter now the default gray); bisection for a table's flat ends;
PhotoCraft spelled with a capital C in the built-in descriptions, with the
shipped coated CMYK profile's bytes as PhotoCraft regenerated them.

Not taken, because craft-cms already does it another way: Curve::inverse_table
(inverse64_many), the effective-dimension loop in multilinear interpolation,
the curve-count and mluc checks, and the .cube DOMAIN writer.

The 8-bit first-stage table checks device white as the exact path does.

* craft-cms: Lut3d::from_fn

PhotoCraft's proof and HDR display tables are built from a chain of several
transforms, which it wrote into Lut3d's fields. Those are private here, so
from_fn samples any RGB function, with the same size bounds as from_transform.
