Issue: #83

I haven't used cmd/login in quite a while. When I run it with this PR I get the following:

go run . -o ~/tesla.token
Username: b****@gmail.com
Password: *********
✔ Passcode: 298871|

2023/05/19 01:30:36 verify: json decode: invalid character 'F' looking for beginning of value
exit status 1

That's strange. I will look into that, but can you provide me with some more information?

• Can you see what you get from the last request in the authentication process?
• Where in the project dose it breake ?

I'm getting the following string:

"Found. Redirecting to /oauth2/v3/authorize/mfa/verify"

From this request:
https://github.com/bogosj/tesla/blob/main/auth.go#L233

Edit: When it attempts to decode the JSON here:
https://github.com/bogosj/tesla/blob/main/auth.go#L244
`

Hey :)
Are you able to test the changes again?
The problem was the MFA verification request needed the _csrf token, and also, there was some issue decoding the MFA Verify response.

Working now with MFA. Thanks for the contribution.
