Update to emoji-regex v9

@Favna wrote a very informative explanation about emoji-regex status and its integration with the emoji image libraries we are using here.

We have now to agree on the direction we want the library to take with that regard. The options I could infer from his writing are:

1. Don’t update to Unicode 13.
2. Update to Unicode 13 but keep EmojiOne on v2 (no Unicode 13 support).
3. Update to Unicode 13 and place a notice about usage of EmojiOne for commercial usage.
4. Update to Unicode 13 and drop EmojiOne.

Please tell me if I’m forgetting anything or you can think of another solution not mentioned above. Looking forward to your opinions.

It sounds like this update necessitates a breaking update as either Emojione is removed or it becomes JoyPixel. I do think there is value in keeping JoyPixel for OSS users and I don’t blame them for having a commercial license. There is a relatively clean way to achieve this:

1. Major version bump
2. Rename emojione -> joypixel
3. Add a prop, something like commercialLicenseAcknowledged – if it isn’t set to true then the JoyPixel render component throws an error.

Thoughts?

Hey @Geczy , I only see dependencies bumps and formatting changes on your fork, but please feel free to work in this issue if you like 😁 (and even better, open a PR so others can benefit from it !)
