Color Profile details are null if string tags are type 'mluc' instead of 'desc'

[bfssamy]

Magick.NET version

13.5.0 Magick.NET.Core

Environment (Operating system, version and so on)

Windows 10/11

Description

ColorProfileData is not correctly populated when type for string tags is 'mluc' rather than 'desc' or 'text'. This is BigEndianUnicode versions of the string which can extend to multiple string for multiple languages.

I have a code fix to return the strings in the first language.

Steps to Reproduce

Any iPhone photo with Display P3 color profile embedded will not populate the data in MagickImage.GetColorProfile() correctly. Apple is using the 'mluc' type for the embedded profile description. This type was introduced in the 2022 version of the ICC 4 spec.

Can you share a file that contains this color profile type? And feel free to create a pull request that resolves this issue.

Hi Dirk, Sure, I'll have to create one - we have had this issue on end user uploaded files so I'll replicate with a file I create myself...it happens from iPhones but may just be HDR images.. I'll get a file that can be used for tests...and I will create a PR for this fix... Thanks, Sam
