do0dle-colors v2.0.0

Changes

• Changed under the hood model to OkLCh and added corresponding methods:

  const color = new Color([.54, .34, 121])
  color.getOkLChArray() // [.54, .34, 121]
  color.getCssOklch() // 'oklch(54% 34% 121)'

• Added new corresponding constructor options for OkLCh:

  new Color([0.56, 0.12, 240], 'OkLCh')
  new Color('oklch(74% .63 210)') 

• Changed default color type to 'OkLCh' when using an array in Color constructor:
• Reworked map functions (mapChroma and mapLightness). Now, at least one property of OkLCh color remains constant, and another property is being changed by a random constant step so that they are evenly spaced from one another.
