Added customizable scopes

[itsMeDavidV]

Edited TeslaAPI enum to include customizable scopes for Fleet API. Did not touch .ownerAPI as Owner API is deprecated and its deletion from this package should occur soon.

Can you add a default Scope to the enum to return all the standard scopes so that we dont need to think too much when adding scopes?

Sure, standard scopes as in just vehicle-related + openid + offline or all?

@itsMeDavidV like adding all to the variable in the enum

Hi, i added myself the static var all so we dont need to set the scopes manually

Nice, sorry about that! Not a lot of spare time these days :/
