[BUG] color is supposed to override colorscheme in SphereStyleSpec and other StyleSpec, but it does not.

[MaximeScope]

Describe the bug
The documentation of SphereStyleSpec indicates that color should override colorscheme. However, looking through the code, it seems that the color is checked first and then colorscheme overrides it, which is the opposite of what is documented.

3Dmol.js/src/utilities.ts

Lines 549 to 552 in 79ccc58

	let color = atom.color;
	if (typeof style.color != "undefined" && style.color != "spectrum")
	color = style.color;
	if (typeof scheme != "undefined") {

Expected behavior
Documentation and code should agree!

Please close your issue when you feel it has been adequately resolved

Like for #726, I'm happy to send a PR for this once we decide on the resolution (modify the code or modify the docs).

Thanks - given that the documentation is wrong, there are zero people relying on it being the way it is while there may be a nonzero amount of code relying on the behavior in the code so I prefer to change the docs (which I've done).
