* nettests/groups.go: remove redundant struct names
* go.mod go.sum: update deps except probe-engine
* Update to ooni/probe-engine@e768161f91
The API has changed. Methods that used to change bits of the session have
been removed. Now the session is more immutable than before.
As such, we need to completely fill the config before using it.
* Set IncludeCountry to always true

* go.mod go.sum: update all non-probe-engine deps
For each line in the go.mod, run `go get -u -v $package` if the
line is not an indirect dependency and is not probe-engine.
Upgrading probe-engine is going to require the same spell that
is used in probe-engine to update psiphon.
* go get -v github.com/ooni/probe-engine@v0.5.0
This just pins to the latest probe-engine but we've not manually
pinned all the other dependencieds yet.
Take care of the trivial API changes in probe-engine as well, such
that we can have a working build after this commit.
* go.mod go.sum: pin to probe-engine dependencies
Basically: remove all indirect dependencies. Merge this go.mod with
the one of probe-engine, to pin dependencies. Run `go mod tidy`.
* circumvention: add basic implementation of tor
This needs to be polished further, of course. But at least we have
now added support for running tor in the circumvention group.
* Readme.md: document how to update dependencies
* go get -v github.com/ooni/probe-engine@fcc9ee0a7afb
* go get -v github.com/ooni/probe-engine@4d254f5b2
* nettests/tor.go: implement summary test keys
