Subject: Add peel_onion_message method to OnionMessenger
X-Git-Tag: v0.0.123-beta~93^2~18

Add peel_onion_message method to OnionMessenger

When testing OnionMessenger in functional tests, it would be useful to
examine the contents of an OnionMessage response. Expose the standalone
peel_onion_message on OnionMessenger to facilitate this.
