Onion Messages: sending, receiving, forwarding, and ancillary utilities live here

Onion messages are multi-purpose messages sent between peers over the lightning network. In the near future, they will be used to communicate invoices for offers, unlocking use cases such as static invoices, refunds and proof of payer. Further, you will be able to accept payments without revealing your node id through the use of blinded paths.

LDK sends and receives onion messages via the OnionMessenger. See its documentation for more information on its usage.
