v1.0.0

A complete redesign of the API.

• Message is not stored as raw bytes internally for minimum memory footprint.
• Retransmission of CON messages is handled automatically.
• The loop takes care of matching ACK or RST messages, removing them from retransmission queue.
• Observer option is supported, together with some utilities to manage the observers (refer to the examples).
• Fully documented and updated examples.
