lua.wire.update
wire.update()
Fetch and process memos, should be called at least once a second to deal with memo replies or callbacks will not fire in a reasonable time.
memo callbacks on_result will only be launched from this function. Note that a result may be a fail if result.fail is set.
After calling this all memos that got a reply will have been removed from the wire cache as we no longer need to deal with them.
