Updated auth to use SSO tokens

[DoctorMcKay]

The owner API now accepts JWTs issued by the SSO server, so it's no longer necessary to exchange the SSO JWT for an owner API-specific access token. This pull request removes that extra token exchange in the login function, and makes it possible to pass SSO refresh tokens to the refreshToken method (it's still possible to pass owner API refresh tokens; this is fully backwards-compatible).

That said, updating the login function is purely academic as it seems that Tesla has added some browser-based security features to the login flow, including recaptcha. It seems that logging in using a non-browser app isn't going to be possible anymore. I've written a Chromium extension that lets you get tokens via the browser, however. It's been submitted to the Chrome and Edge stores and is awaiting review.

Can this PR get merged ASAP? It seems that Tesla has deprecated the owner API authentication in favor of using auth.tesla.com which broke TeslaJS. This PR seems to fix it.

Sorry for the delay. Other projects taking my time. I will have a look and see if I can safely merge it.

I am just wondering if this will be merged at some point?

Any update on this? Seems like a solid fix as the owner API does not work. Would love to see this merged ;-)
