Not Found Component for emoji search

[Rena-Ryumae]

If a user's search returns no results,
the sleuth_or_spy emoji appears. We would
instead like for a custom image to appear.

We propose creating a NotFound component
that uses the the sleuth_or_spy emoji
on default when a user's search returns
no results but otherwise uses what the
user passes through

Changes to note: I made it so when using a custom component, it doesn’t have the emoji-mart-no-results applied. That’s up to the developer to handle spacing / layout correctly when using a custom component.

As a bonus while in that area: I added a notFoundEmoji props to still use the default not found component, but a different emoji (default still is sleuth_or_spy).
