Expand description

Events a pending session can produce.

This represents the state changes a session can undergo until it is ready to send capability messages https://github.com/ethereum/devp2p/blob/6b0abc3d956a626c28dce1307ee9f546db17b6bd/rlpx.md.

A session starts with a Handshake, followed by a Hello message which
