Missing `3DSecure/auth`

[kmi3c]

I believe there is missing client method mentioned in documentation in:

https://paylane.pl/devzone/karty/#3-d-secure-2
There is method #sale_by_3d_secure_authorization which calls corresponding REST API 3DSecure/authSale method but there is no call for 3DSecure/auth.
