dnscrypt-proxy2: Update to 2.0.42

* Version 2.0.42
 - The current versions of the `dnsdist` load balancer (presumably used
by quad9, cleanbrowsing, qualityology, freetsa.org, ffmuc.net,
opennic-bongobow, sth-dnscrypt-se, ams-dnscrypt-nl and more)
is preventing queries over 1500 bytes from being received over UDP.
Temporary workarounds have been introduced to improve reliability
with these resolvers for regular DNSCrypt. Unfortunately, anonymized
DNS cannot be reliable until the issue is fixed server-side. `dnsdist`
authors are aware of it and are working on a fix.
 - New option in the `[anonymized_dns]` section: `skip_incompatible`,
to ignore resolvers incompatible with Anonymized DNS instead of
using them without a relay.
 - The server latency benchmark is faster while being able to perform
more retries if necessary.
 - Continuous integration has been moved to GitHub Actions.
