♻️ Improving tasks for architectural liberty

[Sigmanificient]

Tasks are kinda bound to either to bot or cogs cause of the tasks.loop decorator. Currently, to have all the tasks within a tasks directory, you need a cog and something like this within its __init__:

from https://github.com/Pincer-org/Pincer-Bot/blob/main/pincer_bot/cogs/info.py

from pincer_bot.tasks.get_pypi_downloads import get_pypi_stats

# ...

    def __init__(self, client):
        self.client = client

        task = TaskScheduler(self.client)
        self.get_pypi_downloads = task.loop(minutes=10)(get_pypi_stats)
        self.get_pypi_downloads.start()

A rewrite allowing to have tasks seperated more easily would be great
