Description

Improves PartialEmoji.from_str to handle more kinds of emoji. If no emoji can be parsed, this method now returns None (breaking)

This method can now handle the following payloads:

<:emoji_name:emoji_id>
:emoji_name:emoji_id
<a:emoji_name:emoji_id>
a:emoji_name:emoji_id
👋  # improved
:wave:  # new

Changes

• Add emoji as a dependency
• Update from_str to utilise emoji dep
• from_str now returns None when no match can be found

Checklist

• I've formatted my code with Black
• I've ensured my code works on Python 3.10.x
• I've tested my code
