Support https://emojipedia.org

[Oreomeow]

Hi developer, can you support the emoji under https://emojipedia.org/airplane? For some reason I can't download the emoji images under https://emojicdn.elk.sh/ properly.

I tried to override the get_emoji method under the source.py EmojiCDNSource class, so I found https://emojipedia.org/airplane. I tried to find the relevant python emoji-api library, but only found the npm dependency https://github.com/CesiumLabs/emoji-api. It's a lot of work, so I was wondering if you could support it?
