* Add test-code for pads
* Move test-code into board_test_utils.cpp for reuse, one method per object
* Add a real (rather small) Altium footprint for testing purposes
The test simply loads every footprint of a library, and compares all elements with an equivalent
KiCad footprint. This allows us to quickly spot regressions in the altium and kicad footprint importer,
and any code in-between. This test is only a demo, as the checks are still incomplete and quite a few
tests are missing.
It has to be noted that mask expansion is not supported rigt now by the altium importer, thus the
reference footprint is adjusted to keep the test happy.
