NIP-76: Private Channels - Draft 2 - Includes Client Implementation and Tool kit library

[d-krause]

WORK IN PROGRESS

• More cleanup work to do, but this version can demonstrate basic functionality

Overview

• Each Private Channel message is encrypted with a unique key, signed with another unique key, and reveals no identifying information about the author or the intended recipient.
• Event signatures are verified through channel chainCode key derivation.
• Channel Keys are exchanged via event pointer strings, encrypted (by password or computed secret), which are the keys to a single nostrEvent called an Invitation.
