Revert "Revert "Bump pyo3 from 0.12.4 to 0.13.1 (Qiskit#224)""

This commit restores the PyO3, rust-numpy, and ndarray bump to the
latest versions. This was previously reverted in Qiskit#237 to avoid the
increase in the minimum supported rust version to enable builds on
piwheels. However, now that 0.8.0 has been released I think it's fine to
bump now.

This reverts commit 3beb8fb.
