Add fan animal depiction implications for maribel_hearn and usami_renko

BUR #53597 has been approved by @evazion.

create implication usami_renko_(bird) -> usami_renko
create implication maribel_hearn_(cat) -> maribel_hearn

These are common fan depictions of these two characters.

I dislike tags such as these, because usami_renko animalization and maribel_hearn animalization return more or less the same thing.
If they had more than 50 posts I would be ok with it, but they don't.
