LAB/LCH support via PIL.ImageCms?

[portnov]

python-lcms module seems to be unmaintaned for some time.
Moreover, it always caused troubles on Windows, because it is actually a binding to C++ LCMS library, so one should first build that library on windows.
So it is required to consider a replacement of python-lcms by some pure-python library.

PIL does not have API to convert one color, it can only convert an image.

To consider:

• python-colormath https://pypi.python.org/pypi/colormath - marked as unmaintained, though there are recently applied pull-requests, that gives hope.
• https://pypi.python.org/pypi/colorpy - seems to be unmaintained for a long period.
• http://scikit-image.org/docs/dev/api/skimage.color.html - only can convert whole images.
• https://github.com/jsvine/spectra (it seems to be a wrapper around colormath and https://github.com/xav/Grapefruit)
• https://github.com/njsmith/colorspacious

colormath works fine, but it looks like it is pure python, so it is pretty slow comparing to lcms :/
