Image sprite is too big in size

[amitpatil321]

After bundling my react project, I noticed its size is huge and after analyzing the build I found that quill-emoji sprite is huge in size (almost 7mb).

After compression image become 1.7MB only.
If you want I can create pull request with that image.

Agreed. This is needed. Also, of the list of emotions, it would nice to be able to pick a subset of the
emoticons (e.g. just the emoticon faces), thus reducing the network/load times even more.
