Upgrade mate1600t to master1600t

The only difference in the tests boils down to tide/current problems on the mates test that aren’t on master 1600(terrestrial and chart) and sunrise/sunsets on the 1600 master, not on mate.

Other than a few other minor issues, everything else is the same. Therefore it doesn’t make sense that a crossover exam covering only the additional information is ok for mates but not vice versa.

I agree with a crossover exam 100%
