Converts a color to a hexadecimal string.

If the color has alpha transparency different from 1, it will use the #RRGGBBAA format. Note that the support for that is (as of March 2018) missing on IE, Edge and some mobile browsers. It may be better to use colorToCssRgba, which has excellent support.

colorToHexWithAlpha (rgb  255 0 0)     -- "#ff0000"
colorToHexWithAlpha (rgba 255 0 0 1.0) -- "#ff0000"
colorToHexWithAlpha (rgba 255 0 0 0.5) -- "#ff000080"
colorToHexWithAlpha (rgba 255 0 0 0.0) -- "#ff000000"
