Fixed numpy interface for surface derivative computation; added tests

[jnwalther]

Hi, I was made aware of a bug in the python interfaces for the numpy surface derivative computation, which made me realize that there were no tests. This PR fixes the error and supplements the tests.

Summary by Sourcery

Fix the numpy interface for surface derivative computation and add tests to validate curve and surface derivative evaluations.

Bug Fixes:

• Fix the numpy interface for surface derivative computation by correcting the function signature to include an additional parameter.

Tests:

• Add tests for curve and surface derivative evaluations to ensure correct functionality of the numpy interface.
