test_load_data checks for floating point equality

	assert orig_data.loc[0, "formation_energy_per_atom"] == -0.7374389025000001
	assert reload_data.loc[0, "formation_energy_per_atom"] == -0.7374389025000001

In general, we should never check floating point values for equality. Especially the last six digits look insignificant where the 1 is most likely an artifact of the imperfect floating point representation. Maybe pytest.approx would be a better fit here?

Thanks for the advice! I didn't know about pytest.approx.
