Breaking changes: Remove From/Into implementations of Rgb and Hsl where used non float numbers with passing alpha channel value. ( (u8,u8,u8,u8), [i32;4], etc. ) Because in most cases it is useless. This reduced the compiled lib size: from 952Kb to 780Kb (rlib, rustc v1.47.0)

Add ratio representations of colour models - RgbRatio and HslRatio
