FieldColormapsTask

`construct.field.colormaps`: the field colormaps of libstyle (field-presentation §FVO-2, §FVC-3, matrix FVW-32).

In the namespace construct::opal. Declared in src/libs/libconstruct/construct/opal/FieldColormapsTask.hpp.

Detailed description

Read only. One entry per colormap of style::FieldColormap: `id`, `kind` (sequential, diverging, rainbow, bands), `label`, `license` (an SPDX id), `source` (a URI), `perceptual` (false for a rainbow map, which the menu marks "not perceptual"), and `bands` for a band map, the names of its bands. A plan names a map by its id in the color source, and adds `:reversed` to read it the other way.

Not FEM-guarded: every mesh and tet item can show a field with no solver in the build.
