Extract dominant colors from images using native extension implemented in Rust.

Currently contains four options (ciede 76, cmclc, ciede94, and ciede2000) (all here: https://en.wikipedia.org/wiki/Color_difference), all weighted so that the distance between rgb 0,0,0 and rgb 255,255,255 will be 1.000 (accurate to 4 decimal places). Will add more. All are my own implementations (although ciede2000 is based on several dozen implementations found during research), and they may be wrong because of it. If you see any problems, let me know. Thanks go out to Josh Clayton (https://robots.thoughtbot.com/get-your-c-on), for helping me to understand the structure I was attempting to acheive.
