matlabbe 338e142e58 CI coverage: adding g2o, gtsam, ceres and libpointmatcher. (#1743)
* CI coverage: adding g2o, gtsam, ceres and libpointmatcher. Also fetch test data for integration tests.

* ld

* Increasing ci test timeout for coverage

* Fixed tests when vertigo is not there

* verbose tests

* updating flaky test

* faster coverage by extending unit tests and disable integration test (only for coverage report)

* improving coverage of unit tests in comparison to integrations tests

* fixing not covered new lines
