feat: update csurf -> csrf-csrf

[Benehiko]

Replaces csurf with csrf-csrf. https://www.npmjs.com/package/csrf-csrf

I have also updated the Ory client to the latest version.

Since this is a change in security related packages concerning CSRF protection on the consent endpoint, could you take a look @hperl?

This looks very good, and I might be able to use this lib as well. Looks like it's very versatile. Also, very nice updates to the README.

Have just a few nits.
