3 people bfbc9903d5 cms: accept ICC DeviceLinks whose output isn't a 3-channel PCS (#2348) ...

A DeviceLink's header PCS field holds its output colour space
(ICC.1:2010 §7.2.7), so a CMYK→CMYK link has a 4→4 AToB0. The LUT
channel check hard-coded 3 outputs and rejected such files as invalid,
so users were told a well-formed profile was corrupt and never reached
the "DeviceLink profiles cannot be used" error.

Check DeviceLink LUTs against the header's output space instead, and
only let a Lab DeviceLink through link_stages when its tables end in
3 channels, so a Lab→CMYK link gets the unsupported error rather than
building a mismatched transform.

Fixes #2337
