A bunch of packages (including oohelperd) just need the ability to
use MaxMind-like databases. They don't need the additional functionality
implemented by the geolocate package. Such a package, in fact, is
mostly (if not only) needed by the engine package.
Therefore, move code to query MaxMind-like databases to a separate
package, and avoid depending on geolocate in all the packages for
which it's sufficient to use geoipx.

The T0 field is the moment when we started collecting data, while T
is the moment when we finished collecting data.
The TransactionID field will be repurposed for step-by-step measurements
to indicate related observations collected as part of the same flow
(e.g., TCP+TLS+HTTP).
Note that, for now, this change will only affect measurexlite and we're
not planning on changing other libraries for measuring.

* feat: save CNAME into archival data format
When a DNSResponse contains a non-empty CNAME, we include it
into the related list of answers.
Closes https://github.com/ooni/probe/issues/2227
* doc: add design note
While there, make code more compact and robust to a case where
we're going to extract additional answers.
* doc: document the expected growth of extraction function
Based on feedback by @DecFox
* feat: add support for system resolver in measurexlite
* more tests for coverage
* Apply suggestions from code review
