decomposeColor has null value when string has whitespace

[rdougan]

Steps to reproduce

Steps:

1. Open this link to live example: https://codesandbox.io/p/sandbox/blissful-fog-kc3xy8

decomposeColor('#aa0099 ');
//{"type":"rgba","values":[170,0,153,null]}

darken('#aa0099 ', 0.5);
//rgba(85, 0, 76, NaN)

Current behavior

Alpha value returned by decomposeColor is null when the color string passed has whitespace before/after value. Due to this, darken (and probably other functions) return NaN when calculating proper values.

Expected behavior

Trim whitespace, or give a warning in the console.
