remove implication bat_wings (14675) -> wings (433270)

Reason: already implicated through membranous_wings

(I do wonder whether we need this tag at all though. maybe we'd be better off having a tag for that thumb regardless of what kind of wing it's on)

I suppose if we want to ak-shoo-ally it, pterosaur wings also count as membranous, and they're arranged differently than bat wings (the wingfinger is the pinky instead of all the non-thumb digits). However, I don't think there are all that many pterosaur wings on the site (beyond those attached to pterosaurs).

There are a lot that are definitely not bat wings, which have the membrane stretched between fingers:

"What if they were intended to be bat wings?" Well they don't look like bat wings. Some might be anatomical errors, but others are intentional. They were probably all inspired by bat wings, but we don't tag every pointy knotted cock canine_penis because some just aren't:
