frog_crab about frog_emojis

@Miepee do you have any improvement ideas over the crab shape or should I just go ahead and do an initial vector PR
Reviews can be done over the vectorized version still

[Miepee]

I personally prefer if the twemoji crab would be used rather than the random clipart, for consistency with other emojis. Although the "feel" of that is pretty different so people might not like it as much.

Apart from that, not really though

I would prefer a more ferris like version
But we can always do 2 versions
one for logos/ and one in root

I guess I will do the ferris one for now, since it has the most applications.

[Miepee]

A ferris variant is fine by me.

[Riesi]

Ok
lets see how that will pan out
we can move to 2 versions later anyways
