Add websocket support for @caravan/clients and coordinator

[bucko13]

Currently all client connection options rely on HTTP requests for interacting with the blockchain network. The public client options mempool.space and blockstream.info however are subject to rate limits to deal with heavy traffic which can make them unreliable for querying balances one address at a time (and other network requests that need to be made).

Mempool.space has recently made available a websocket client MWCK which offers a solution as it get query wallet data with fewer connections.

Currently though the @caravan/clients library is built only to support individual HTTP requests and @caravan/coordinator is built around this expectation, updating information about individual addresses for each one off request.

We would like to first add support to the clients library for a generic websocket interface that can leverage MWCK, and then update the coordinator wallet to use this.
