The test currently fails due to a floating point rounding error. I'll give it some lenience, especially since both the ground truth and the supposed output are estimates.
It will set up a very basic g-code planner and let it estimate the time and material it needs. Currently it only tests with empty g-code, but I mean to add a test with retraction once this works. Currently the setup gives a segfault.
