An interactive dice roller COG for Discord.py Bots

Setup

1. Have a Discord.py bot (Quickstart available at https://discordpy.readthedocs.io/en/stable/quickstart.html)
2. Assuming you're using the minimal quickstart bot, place the cog in the same folder as your bot.
3. Add client.load_extension('COG_interactive_dice_roller') somewhere in the code of your bot.
4. Run the minimal bot.
5. Type !r or !roll in the Discord server chat where the bot is setup to see the dice roller in action.
