alternative x=x fix, plus handling {cluster} better

[mitchest]

So, I think a more elegant way of handling the x=x thing, additional to what you've done, is to also remove a default argument binding from get_colors_from_map(). I also wanted to try moving cluster back to Suggests: and try handling it with requireNamespace() - more for my own testing, rather than it actually being important for earthtones haha
