Tesla Authentication (March 2022)

Hi everyone.

Just a heads up that I have finally got some code working for the new API authentication that Tesla broke last year.

It's currently offline in Python 3 (terminal) but shouldn't be too difficult to replicate into the plugin once Matt/Jay let us know what's happening with Indigo.vNext()

@GlennNZ feel free to get in touch if you want a heads up on it.
