Adds support for np.gradient through the existing frameworks for the array api. This PR also adds its own version of np.diff, as the one in the server does not work with gradient. This is a fast workaround, the diff server function should just be made to work properly (and then exposed via
__array_function__
).This PR also changes the implementation of
empty_like
to usezeros_like
, as the implementation before did not actually register a new array with the server.TODO: add testing for the various functions added.
