Methods that return instances of `Friend` raise `KeyError`

[Jodenee]

Describe the bug
A recent change to the Roblox API has brokenBaseUser.get_friends due to the endpoint no longer returning most fields.

To Reproduce

import asyncio
from os import getenv
from dotenv import load_dotenv
from roblox import Client
from roblox.users import User

load_dotenv()

client: Client = Client(getenv("COOKIE"))

async def main():
    user: User = await client.get_authenticated_user()

    print(await user.get_friends())

asyncio.run(main())

Expected behavior
A list of Friend instances is printed to the console.

Desired solution
BaseUser.get_friends() should return a PageIterator of BaseUser instances.

Along with this update a new endpoint has been added /v1/users/{userId}/friends/find which can be used to replace the old endpoint /v1/users/{userId}/friends.

Reasons to switch

• userSort param has been deprecated on the old endpoint.
• The new endpoint is paginated while the old endpoint returns a huge list.
• The old endpoint is capped at 200 friends, so when the max friend limit is raised it will still only return 200 friends.
• The new endpoint provides a more accurate FriendScore for sorting.
