Refactored /g into /chat and /gpt-chat into /converse
Both have the grouping "gpt" so the full is /gpt chat, and /gpt converse
Added pycord-multicog to the project for easier slash grouping across cogs
Made the role check case insensitive and added some comments to the sample.env
Removed the rest of the discord.ext imports, it's not really used, ymmv
Removed another admin check i had missed in local-size
