Fix compatibility for binary operations

[ollyfutur]

Hello,

Binary operations on two Grid objects with different edges parameters should raise a TypeError as stated in the docstring of Grid.check_compatible.

This pull request implements the expected behavior, and also allows operations with non-Grid objects that are broadcastable to the Grids shape, such as numpy.ndarray. This is why I removed the test

            data['grid'].check_compatible("foo")

since the string "foo" is broadcastable to any array shape, it does not raise in check_compatible (an error will probably be raised downstream anyways for any such operation).

I also modified the docstrings accordingly and added a couple of tests.
