Version 1.0.0

This is a new and shiny first major release for `metarhia-jstp`.
Changes include API refactoring and improvements, implementations of
CLI, sessions, and application versions, native addon build optimizations,
lots of bug fixes, test coverage increase, and other, less notable changes.

This release also denotes the bump of the protocol version to v1.0.
The only difference from the previous version of the protocol is that
"old" heartbeat messages (`{}`) are now deprecated and `ping`/`pong`
messages must be used for this purpose instead.
