Update TeslaFi importer to accept newer export formats

[ithinuel]

I am not sure if using "1" as the default id but that's what's suggested in #3158 (comment) and has worked so far.

Is the ci failure related to the changes in this PR?

As far as I can see: no. see #3428

It is not stale.

To summarize the pending thread:

• @JakobLichterfeld does not want to see a hard codded value for the vehicle_id
• This vehicle_id is not exported in TeslaFi’s data exports.
• In the context of the TeslaFi importer, the input data come from TeslaFi so whether the vehicle_id is present or not in Tesla’s own api is irrelevant
• As far as I understand, Teslamate relies on the JSON API’s id, not the vehicle_id.

So, is this field essential for the purpose of TeslaMate? Could it be made optionnal and left empty by the importer?

Still waiting far input from reviewer.

LGTM, it's much faster than adding the value in x large csv files by hand...

It might be useful to mention the TESLAFI_IMPORT_VEHICLE_ID in the documentation to show that we can use this env variable to choose the vehicle id on which to import the data (may be in the Requirements section of this file website/docs/import/teslafi.md)

[JakobLichterfeld]

Thanks. Lgtm. Please also add a description about the env file in the doc, under Environment Variables and additional mention it on the doc page for tesla fi import
