Discord.py: Get Role by Role Name, ID or mention

example-cog-usage.py

import re
import discord

"""
A function that returns the matching role-id(s) in a list (as integers)
Needed Arguments: Comamnd-Context and Role-ID/ Role-Mention/ Role-Name (as a string)

The function will return a tuple of values that contains two values:
- A list with all matching role-id (should be one most of the times)
- The length of that list as secondary return value

Notice: By passing a name into the function you might get more than one result, keep this in mind!

Exaple call: role, length = get_rid(ctx, role_name)
