ICC: Add Profile::to_lab()
...
This can be used to convert a profile-dependent color to the L*a*b*
color space.
(I'd like to use this to implement the DeltaE (CIE 2000) algorithm,
which is a metric for how similar two colors are perceived.
(And I'd like to use that to evaluate color conversion roundtrip
quality, once I've implemented full conversions.)

ICC: Add method to convert a color to the profile connection space
...
Only implemented for matrix profiles so far.
This API won't be fast enough to color manage images, but let's
get something working before getting something fast.

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: Move ICC::Profile::read_header() out of class
...
This one is slightly more involved: To make it nice, extract
all the Profile fields that belong to the header into a separate
struct.

LibGfx: Split ICC/Profile.{h,cpp} into several files
...
s15Fixed16Number and XYZNumber are somewhat awkwardly duplicated
in both Profile.cpp and TagTypes.cpp. Other than that, this is a
pure code move.
No behavior change.
