[Bug]: Cardano chain follower fails to set read pointer

[FelipeRosa]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

Follower fails if a set read pointer request is received when it's waiting for a response from the node.

NOTE: seems that pallas client can't be used concurrently.

Expected Behavior

Follower should cancel the current request (or wait for it to be complete) and handle the set pointer request correctly.

Confirmed that the problem is related to the way the PeerClient (from pallas) is being used.

The chain follower tries to execute a intersect point request while the client is in the middle of receiving a chain update from the node. This causes the set_read_pointer to fail.
