This also adds additional capabilities to icc profile generation, which previously was lagging behind its ociobakelut cousin. (Specifically in terms of Config-Free LUT Baking Options.)

I'm open to suggestions whether the removal (merging) of a previously supported command-line tool is appropriate for a minor dot-release. My instinct is that this is ok, but if people have objections I'd also be ok with keeping ocio2icc around and marking it deprecated.

ociobakelut -- create a new LUT or icc profile from an OCIO config or lut file(s)

usage:  ociobakelut [options] <OUTPUTFILE.LUT>

example:  ociobakelut --inputspace lg10 --outputspace srgb8 --format flame lg_to_srgb.3dl
example:  ociobakelut --lut filmlut.3dl --lut calibration.3dl --format flame display.3dl
example:  ociobakelut --lut look.3dl --offset 0.01 -0.02 0.03 --lut display.3dl --format flame display_with_look.3dl
example:  ociobakelut --inputspace lg10 --outputspace srgb8 --format icc ~/Library/ColorSync/Profiles/test.icc
example:  ociobakelut --lut filmlut.3dl --lut calibration.3dl --format icc ~/Library/ColorSync/Profiles/test.icc
