v0.13.10

• Add an additional error code (ErrLinkDetached) that will be returned by Send() if the link is detached at the start of the call. Prior to this the caller would return the last received error on the link, which did not indicate that the link itself was closed/detached.
• Sender now has a new function (Id) that gives you the internal link ID. This can be used by callers (like Azure Event Hubs) that want to checks on whether they need to recover a link by doing a simple ID/string check.
