Does not announce services without a Service Type Enumeration query first
Describe the bug
The PTR records are not announced for services unless a Service Type Enumeration query (_services._dns-sd._udp.local) is sent on the network.
To Reproduce Steps to reproduce the behavior: Start MdnsLite with services defined BUT no devices on the network that will conduct a Service Type Enumeration.
Expected behavior When MdnsLite starts and an address is acquired for the interface the service announcement should be conducted.
The mDNS RFC does provide some guidance for announcements in https://www.rfc-editor.org/rfc/rfc6762#section-8.3. A PR that implements the startup announcement would be appreciated. I'm not sure that this fixes your issue, but it seems like it would help.
From what I can see there is no unsolicited announcement, correct?
Also, I have looked through the code some and it is not clear where this may get added. If you could offer a couple of suggestions I am happy to take a look at making a PR.
