MyCupra API Error

[jnsflschr]

Describe the bug When the MyCupra Session Api is used every call will get a 500. Maybe there are some headers missing but without any documentation there is no way to fix this for me. I used the changes of the branch below to use the already implemented api.

To Reproduce

1. merge in branch derco0n:cupra_testing
2. execute allVehicles.py

Expected behavior Return all vehilcels of the MyCupra account

Additional context My goal is to get the data from my Cupra Leon ST (gasoline). If I use the default api is I get an empty list returned. I suppose its because the data is saved at the MyCupra api. That's why used the approach from @derco0n
