create implication seiza -> legs_together
Can thigh_gap exist without legs being together or thighs touching?
I think that is unlikely - same can be said for seiza with it's strict implications.
Currently there's no implications for legs_together tag, even though it's quite useful for pose description.
IMO it can also be used together with knees_together_feet_apart or pigeon-toed for more detailed pose tagging, but currently that would contradict guidelines in wiki page. I find it weird since there are posts tagged pigeontoed varying for everything from "legs together slightly inwards" to "kneeling with feet wide apart" or even sitting with legs and knees apart.
Maybe that can also be discussed here?
