1.4.0

What's Changed

• @kriptonix relay responses handling by @Sebastix in #60

The library now provides separate relay response classes according to NIP-01.

• EVENT - sends events requested by the client
• OK - indicate an acceptance or denial of an EVENT message
• EOSE - end of stored events
• CLOSED - subscription is ended on the server side
• NOTICE - used to send human-readable messages (like errors) to clients

This replaces the CommandResult class which had the response of a relay. Thanks @kriptonix for working out the initial codebase in #59.
