Incorrect gradients

[gmcusaro]

Trying to make a simple gradient between red #ff0000 and blu #0000ff with color spaces HSL and HSB I have an unexpected result. It seem works correctly with RGB and L*a*b*.

Expected behavior should be similar to RGB and L*a*b* spaces.

Additional considerations:

• For HSL color space, increasing the steps the gradient seems to make the opposite turn of the wheel instead of the shortest way.
• For HSB I cannot understand which way is used.

Maybe this func could have a bug: mixedHue(source: CGFloat, target: CGFloat) in DynamicColor+Mixing.swift
