Upgraded emoji list and improved performances

[ipodishima]

Hey there

Not sure this repo is still maintained, but I needed some updates for a project of mine.

What's new in this upgrade:

• updated the python script to work with the latest version of MacOS
• upgraded the emoji list with the latests from emojione
• fixed an issue with regex and shortnames like +1
• added support for shortnames_alternates (ex: +1 was not recognized but thumbsup was)
• updated the way we create the emoji map table. Was an array of struct, is now an enum. Should improve compilation but we lose the "add a custom emoji feature"
• Upgraded the way we deal with escaping / unescaping. Improved performances by 70% for unescaping and 86% for escaping (yai)

I'm all ears

It looks nice😍, though we lose custom emoji feature. Thanks!

You're very welcome! Yeah, I wasn't sure about the use of custom emojis but the speed improvement was so huge it was worth it for my project :)
