This PR adds utilities for doing finite difference tests for the metatensor-operations and uses them in the simple example of the
add
operation.This is the first PR addressing issue #84
The idea of the testing utilities originates from issue #469
In the next run on this PR I want to dispatch the testing utilities so they can also be used for torch, but before that I would like to have some general feedback if this is going in a good direction.
