## Summary

This diff changes the `summary.go` algorithm of Web Connectivity v0.4 to
handle `android_dns_cache_no_data` as an anomaly when the DNS is
inconsistent. We continue handling `dns_nxdomain_error` as an anomaly
when the DNS is inconsistent, as demonstrated by the fact that the
corresponding netem test is still passing.

This diff also bumps the version number to v0.4.3. Version v0.4.2 did
not handle this case, which caused measurements to be marked as failed
as documented by https://github.com/ooni/probe/issues/2499.

This diff is also related to https://github.com/ooni/probe/issues/2029,
in the sense that it is slightly improving our analysis results when the
is an NXDOMAIN error (even if it's masked by Android's DNS cache
behavior).

While there, add empty lines to improve the code readability.
