This is useful when someone is running manual measurements and is
sharing their measurements with us, because it means we don't need
manually keep track of this bit of information.
Closes https://github.com/ooni/probe-engine/issues/1194
* refactor: miniooni should be outside of the engine
This is part of https://github.com/ooni/probe/issues/1335. We also need
to think whether we wanna keep libminiooni and miniooni separated.
The previous use case for having a top-level libminiooni was that of
enabling others to integrate miniooni into other binaries.
This was usegul when studying internet censorship in Spain in May 2020.
I am wondering whether we should be keeping this complexity. I am not
sure about this and probably we should be killing it.
(In any case, reducing complexity is not the objective of this diff,
since I would like instead to move things around with minimal changes
and make sure we have a ~good repository organization here.)
* fix: import in libminiooni
