Extend the ranges of emojis that are supported, listed
[below](#new-emojis-supported).
To ensure that single `char` emojis are supported, the `emojis` crate
is added as a dev dependency, using it to check that a `Reaction` can
be constructed for the two groups `SmileysAndEmotion` and
`PeopleAndBody`.
