Convert to HSL

[eknowles]

Look at simplifying the algorithm to a string to number between 0-359 for hue.
The user can then request a saturation, lightness, alpha separately.

e.g.

convert(hue: number | boolean, saturation: number | boolean, lightness: number | boolean)(str: string)

create the factory fn first with your rules.

if first arg is true then a number will be generated for the string
if false it will use the default (hue: 50 saturation: 100, lightness: 50)
when given a number it will fix as that.

this could be useful when have different color groups. i.e. in data visualisation for subgroups.
