[Feature] Spectrum/Sequence of Colors

[unenglishable]

It would be interesting to use a (definable) sequence of colors as opposed to just Even/Odd.

Line: 1, 2, 3, 4, 5, etc.

Color: 1, 2, 3, 4, 5, etc (mod Color length)

I'm not sure how to implement this, but if anyone has any ideas, I'll try it out and put in a pull request if it turns out well.

I'm going to throw my hat in here and say this would be great. An idea would be to have "palettes" that the user could configure. Example:

" Set of 'solar' guide colors; e.g. red, yellow, orange
let g:indent_guides_palette = "solar" 
let g:indent_guides_palette = "monochrome_dark" 
let g:indent_guides_palette = "monochrome_light"

" Let users specify a list of colors
let g:indent_guides_palette = {'c93bac', 'a01070', '930054'}

I personally don't think it is a great idea to hard code some specific color scheme or schemes into this plugin, but I would be willing to facilitate a PR if somebody wanted to make it more configurable. In particular the color selector could be changed to either use a lookup table (with a modus for overflow handling) that the user could provide to match their preferences or it could just be a hook function that gets used if set. Then people could return colors however they want programmatically.

I'm unlikely to work on this myself but will facilitate a PR if somebody works something up.
