Here we provide a workaround for servers that don't follow the JSON-RPC 2.0 specification for error objects. According to the specification, an error should be an object containing `code`, `message`, and `data` properties (see: https://www.jsonrpc.org/specification#error_object). Unfortunately, Electrs returns an error as a string (see: Blockstream/esplora#453). We define an error unmarshaling function to handle both types of errors.
It would be usefull to include value that failed unmarshalling in the debug mode log message.

Here we add support for WebSocket protocol. With this change the client will support all connection types defined by the electrum protocol: `tcp`, `ssl`, `ws` and `wss`. The WebSocket client initialization expects remote server details to be provided as URL including a scheme and host, e.g. `tcp://electrum.io:50001`.
The `NewClient` function should be used to initialize the client. The function resolves transport protocol from the URL. It supports all four protocols: `tcp`, `ssl`, `ws` and `wss`.
After sending a close message to the server we need to wait for the response or force the conncetion closure after a timeout.

Hotfix/data race
The `SubscribeHeadersSingle` function subscribes to receive the header of the current blockchain tip. Unlike `SubscribeHeaders`, this function only returns the tip and does not listen for new block headers. Worth noting that this action still creates a new subscription in the Electrum server. The protocol does neither support a single-shot request for the current blockchain tip nor subscription cancellation. Although this limitation causes a slight resource overhead on the client, it does not cause a memory leak like the `SubscribeHeaders` method which spawns a goroutine that may hang on the channel if the caller is no longer pulling from it.
