feat(GradientTexture): Support any color representation

[lukehorvat]

Why

A small tweak. GradientTexture currently only supports string colors, meaning you cannot use other Three.js color representations like number or THREE.Color.

<GradientTexture colors={['#7cbfff', '#fff']} stops={[0, 1]} />

What

Add support for any valid color representation.

<GradientTexture colors={[0x7cbfff, '#fff']} stops={[0, 1]} />

<GradientTexture colors={[new THREE.Color().setHSL(0.6, 1, 0.6), '#fff']} stops={[0, 1]} />
