The pubsub client provided by solana/agave crates fails silently: https://github.com/anza-xyz/agave/blob/79c0fe5c7cfc94e921a104c4e51e2e27aee9d821/pubsub-client/src/nonblocking/pubsub_client.rs#L489
It also does not provide any method to handle disconnection events.

To work around this drift-rs eagerly initializes new PubSubClient instances when a disconnect is detected.

1. Its not clear that all disconnects are being detected properly
2. each instance of PubSubClient creates its own Ws connection with various overhead such as ping messages, etc.

Ideally, drift-rs would multiplex a minimal number of Ws Connections and handle the disconnections properly
