we need a provider to read data when the user os not logged

[Viterbo]

Overview

We need a way to read data from the EVM contracts and currently we rely on the account authenticator. The problem is that this is only present when the user is already logged leaving out the case when the user is not logged and we need to query som data from a contract.

Acceptance Criteria

• The Antilope library should provide a simple function getProvider that returns the best solution found but always returns something useful.
