Fix ServiceBrowsers not getting ServiceStateChange.Removed callbacks on PTR \ 
record expire

ServiceBrowsers were only getting a ServiceStateChange.Removed callback
when the record was sent with a TTL of 0. ServiceBrowsers now correctly
get a ServiceStateChange.Removed callback when the record expires as well.

Fix missing minimum version of python 3.7
