[Suggestion] Pick a built-in theme depending on an image colorscheme

[drybalka]

Sometimes pywal generates a colorscheme that is too monochrome, especially on images with one dominant color. In these cases syntax highlighting is much less useful and I prefer using one of the built-in themes. The problem is that there are several hundreds of them and it is hard to find "the best" one.

I wrote a small script (https://github.com/drybalka/wal-theme-picker) that fixes this problem and suggests a few best-fitting built-in themes based on the image dominant colors. If you are interested, i can try incorporating this script into the code of pywal.
