Add some neopronoun roles to Dynobot on the discord server

[Camryn]

It'd be relatively simple to add some common neopronouns to dynobot's list of self-assignable roles.

Some common ones from another server I'm in:

Ae/aer
Fae/faer
Shi/hir

I can't see any real reason not to include these roles since it would only take a few minutes to add them to the bot. Plus, I'm sure some of our members will be positively ecstatic to be able to use them.

Seems like a win-win to me
