Reusing function for task 1 and task 4

Rewriting http code to use aiohttp instead of requests, as per this article: https://realpython.com/async-io-python/
Python 3.9 asyncio has to_thread() -> could be possible to use requests without to much hassle

had issues with using only one ClientSession in aiohttp. Works better when creating
one ClientSession per request. Might be related to this bug?

According to this (https://stackoverflow.com/questions/62412754/python-asyncio-errors-oserror-winerror-6-the-handle-is-invalid-and-runtim),
there is an issue with the default event loop on Windows in Python 3.8+.

By changing the default event loop, I solved the issue with the weird exception:
asyncio.set_event_loop_policy(asyncio.WindowsSelectorEventLoopPolicy())
