Add support for OOB multi-factor authentication [SDK-2657]

[lbalmaceda]

Changes

The SDK supports logging in using OTP MFA, without a prior challenge request if the OTP factor is known to be available.

This PR:

• adds support for making a challenge request for the server to send the code via a specific authenticator (i.e. SMS, voice, push, etc) and
• adds support for completing the authentication request using that received OOB code.
• updates the dependencies to the versions suggested by the IDE.
