Export colorspaces as constants?

[donmccurdy]

In this section of the types —

three-ts-types/types/three/src/constants.d.ts

Lines 319 to 322 in 56ec692

	export type ColorSpace = NoColorSpace | SRGBColorSpace | LinearSRGBColorSpace;
	export type NoColorSpace = '';
	export type SRGBColorSpace = 'srgb';
	export type LinearSRGBColorSpace = 'srgb-linear';

The colorspaces are exported only as types, not values. As a result, TypeScript will complain if users do this:

color.setRGB( r, g, b, 'srgb' ); // ✅ OK
color.setRGB( r, g, b, THREE.SRGBColorSpace ); // ❌ ERROR

'SRGBColorSpace' only refers to a type, but is being used as a value here.ts(2693)

I think we'd like to allow both, but I'm not sure how to structure that in the TypeScript declarations.
