Add option to copy the emojis codepoint

[sascha-wolf]

There are situation where I'd like to access the codepoint instead of directly copying the emoji.

I'd be happy to provide a PR, assuming somebody can give me some pointers on how to get started. 🙂

The majority of the PR would be figuring out how to implement it. Is there a specific question you have around "getting started"?

[sascha-wolf]

I haven't taken the time to dig into the codebase yet. When I asked for pointers I was hoping for some guidance on the general structure and where the implementation of this feature would best live. 🙂

https://github.com/jsumners/alfred-emoji/blob/master/src/emoji.js is the main entry point. The other scripts in src/ provide implementation details.
