Allow picker to display emoji natively

[tracker-common]

Allow picker to display emojis native rather than just through the sprite sheet.

Just a note: Haven’t forgotten about that PR, I would really love to have that in EmojiMart. Last time I tried, there was some layout issues (namely when hovering the emojis) when using native emojis in the picker.

That being said, I haven’t gotten around to checking with your changes. Will try to do that very soon!

@EtienneLem - no worries. Downloading the image sprite sheet was too slow for our product, so I think this will be a good addition. There was a css change that I probably should have submitted to make the layout better. Chrome doesn't kern emojis correctly, so in our css we had to add this to make the circle'd highlights better.

.emoji-mart .emoji-mart-emoji {
padding: 6px;
cursor: pointer;
width: 32px;
}

@EtienneLem Had a chance to look at this yet? Just pinging this PR again. We'd love to have this merged upstream.

@EtienneLem Just noticed this one had a merge conflict from the previous PRs. I can resolve the conflict in the next hour or so and then you can decide to merge or not.

No worries, I can resolve it. Got to check the CSS too. You could however either give me access to the PR or I can merge manually w/ my changes.

It looks like the "allow edits from maintainers" box is checked on the original PR, so you should have access to modify it.

Looks great on my end, thanks so much! 🤘
