Support advanced key listing #333
Description
The read-only methods of the Wallet Provider are nice because they automatically target the node chosen by the user in their wallet when supported. This is particularly useful when the user runs a trusted local node.
getStorageKeys is already supported. However, it does not support all the newly introduced manual pagination features.
It would be important to add that support, either to that same method in a retro-compatible way, or to a separate method if argument retro-compatibility is not possible.
