Heterochromatic eyewear and asymmetrical eyewear

BUR #14915 has been rejected.

create implication heterochromatic_eyewear -> asymmetrical_eyewear

Heterochromatic implies asymmetry to be present.

However, keep in mind we can separate the two if that is the site's preference. Personally, I'd prune asymmetrical from heterochromatic eyewear that has the same shape, and clarify it in the wiki for the tags.

I think it would be more useful for asymmetrical_eyewear to refer to the frame shape, with lenses being their own thing.
