Update login function to allow the use of a browser cookie to aid in logging in

[mnasra]

This also adds better error messaging when getting a 403 from the FPL API.

I've found logging in with this package no longer works, the workaround is to pull your own browser cookie and inject it into the response headers. This PR includes the ability to grab a cookie from the FPL_COOKIE environment variables and add it to the headers if specified.

I've found this allows the login + associated functions to work properly

I'll merge this when I wake up tomorrow morning and create a new release, thanks!

Hi @mnasra, may I know how do you define the cookies? This is my code:

import asyncio

import aiohttp
import fpl_credentials
from fpl import FPL


async def main():
    async with aiohttp.ClientSession() as session:
        fpl = FPL(session)
        await fpl.login(
            email=fpl_credentials.EMAIL,
            password=fpl_credentials.PASSWORD,
            cookie={
                "pl_profile": "fpl_credentials.PL_PROFILE",
                "datadome": "fpl_credentials.DATADOME",
            },
        )
        league = await fpl.get_classic_league(314)


asyncio.run(main())

I got this error:
TypeError: Cannot serialize non-str key

I need to use this to make it works.

I logged into the FPL website and used a Chrome extension to extract my cookie which was a a long string and then set this to FPL_COOKIE within my environment variables.

I don't think setting it to a dictionary would work it has to be a string in the way I wrote it

I also get the cookies from Chrome. Can you please share me how you set the FPL_COOKIE? An example of your used command might be helpful.

In windows I search "Edit the system environment variables" and put it in "environment variables". Variables = FPL_COOKIE and value = what I extracted from chrome

Hi @amosbastian, I noticed the documentation is outdated. I guess this is because the docs is failing (based on the readme). I wish to contribute. Is there any log I can refer to?
