Support new Tesla-API authentication

[datMaffin]

I was asked (by family) to check whether I could update this program to use the new authentication API as documented here:

• https://github.com/timdorr/tesla-api
• Rendered documentation of the authentication section

However, I currently do not have the required time (I, for example, do not have experience with Perl nor a Tesla account to test with).

My findings are below:

The tesla-api documentation does look like it is sufficiently complete.
In addition, the repo provides an implementation of the API using Ruby:

A diff with the before/after of the authentication implementation can be seen here: https://github.com/timdorr/tesla-api/compare/75e79d34fdbfbfd4ef5978ae45e6bbef96ac4ed5...master?diff=split#
The relevant file is lib/tesla_api/client.rb.

Observed changes (and rough commentary based on a first glance):

• refreshing the authentication token https://github.com/sw-home/FHEM-Tesla/blob/master/FHEM/49_TeslaConnection.pm#L189 is comparable to the tesla-api function refresh_access_token:
  • the tesla-api had some generally minor changes
  • the tesla-api calls a function with the nameexchange_sso_access_token at the end
• getting the authentication token https://github.com/sw-home/FHEM-Tesla/blob/master/FHEM/49_TeslaConnection.pm#L111 is comparable to the tesla-api function login!
  • the tesla-api added a bunch of http calls and result parsing...
  • the tesla-api calls a function with the name exchange_sso_access_token at the end
• tesla-api introduces a new function exchange_sso_access_token
  • looks like a fairly simple http call

The main job seems to be the parsing/scraping of the HTTP results.

Hi, is there going to be an update here?
