py-zeroconf: updated to 0.26.0

0.26.0:
Fixed a regression where service update listener wasn't called on IP address \ 
change (it's called on SRV/A/AAAA record changes now).

Technically backwards incompatible:
Service update hook is no longer called on service addition (service added hook \ 
is still called), this is related to the fix above.
