v1.0.0

Initial release based off of trust-constr from SciPy 1.6.0

The tolerance on a couple of tests needed to opened up compared to the SciPy version. Most likely due to differences in the factorization_method routines needed to remove SciPy dependencies. With those adjustment to the test tolerances, it passes all of the relevant SciPy tests for the 'trust-constr' algorithm. All support for sparse matrices has been removed to remove the SciPy dependency.
