LibGfx: Dedupe identical tag data objects when writing ICC data
...
With this, common v4 profiles, such as embedded into jpgs by iPhones
(when configured to write jpegs) or Pixel phones, are identical to
the input when reexported :^)

LibGfx: Implement serialization of ParametricCurveTagData
...
With this, simple v4 matrix profiles using parametric curves, such as
Compact-ICC-Profiles/profiles/sRGB-v4.icc, can be completely serialized
and the serialized file can be read again by `icc` :^)

LibGfx: Add scaffolding for writing tag data
...
This doesn't deduplicate identical TagDatas yet.
It also doesn't implement actual serialization of TagData yet.

LibGfx: Write ICC tag table
...
All offsets and sizes are set to 0 for now, so this still doesn't
produce a valid icc file. It gets closer, though.

LibGfx: Add start of an ICC profile writer
...
For now, this can write the profile header.
`icc` refuses to dump its contents since the required copyrightTag,
profileDescriptionTag, and required per-device-class tags are missing,
but it looks ok in a hex editor.
