Add information to the documentation about the ability to use with Cookies

Today was actively testing this library for active use in my large projects and microservices.

The documentation does not say that this package can take token from Cookies, but it turned out to be true, initially I wondered whether I should use it, as there was no information about this feature =)

Please don't drop support for this fork, I really want to see something stable and developing in this direction <3
