0.9.8: test fails with montage-4.0

[olebole]

When testing the wrapper with the new version 4.0 of Montage, the numbers seem to have shifted a bit, causing the unit test to fail:

montage_wrapper/tests/test_wrappers.py::TestMosaic::test_mosaic FAILED
montage_wrapper/tests/test_wrappers.py::TestMosaic::test_mosaic_background_match xfail

Similarly for np.mean and np.median.
Increasing the rtol to 1e-5 for al three asserts helps here (by keeping compatibility with the old Montage version).

That problem has disappeared somehow, Montage-wrapper works fine with Montage 5.0 and 6.0. Closing.
