Add relate tests

[michaelkirk]

This PR adds support for the relate tests.

The sister PR which implements this functionality in geo is at georust/geo#639

Looks great! I didn't get to running the tests, but I assume all the tests are now passing. Nice work @michaelkirk !

Yep, all the tests pass, though be aware of one peculiarity -

cd jts-test-runner; cargo test runs more JTS test cases than cd geo; cargo test

This is because the jts-test-runner/Cargo.toml is patched to point to your forked WKT which can parse more tests.

All the tests pass in either case, but something to be aware of.

I realize we don't yet test the Contains trait directly here (as it doesn't have all combinations implemented yet). For now, I tried to manually match the subject and target in Operation::Contains like so:

let verify_contains_trait = match (subject, target) {
    (Geometry::Point(subject), Geometry::Point(target)) => { subject.contains(target) == relate_actual }
    // ... all combinations that have contains implementation ...
    _ => { true }
};

Fortunately, it didn't trip any of the tests, so that's good.

@michaelkirk If it makes sense, you could merge this PR into this branch before merging to master. It just manually checks the Contains implementation for the combinations where we have the trait implementation. This is useful as we don't always use Relate in impl Contains. It might also come in handy to check which combinations are yet to be implemented.

Good call. Done and thank you!
