Release 1.1.0

This release incorporates the functionality added in PySTE v1.1.0:

• Added evolved_gate_infidelity() to calculate the gate infidelity of a unitary generated by a system Hamiltonian.
• Added evolved_inner_product_all() to calculate the inner products of a state vector at each time step during its evolution with some fixed vector.
• Added evolved_inner_product() to calculate the inner product of an evolved state vector with some fixed vector.
• Added gate_gradient() to calculate gradients of the average gate infidelity.
• Added get_evolution() to generate the unitary describing the systems’ evolution.
• Added unit tests for these functions.
• Version pinning requiring py-ste >= 1.1.0, < 2 has been added.
• Updated the GitHub actions:
  • actions/checkout@v4 → actions/checkout@v7
  • actions/setup-python@v5 → actions/setup-python@v6
  • actions/upload-artifact@v4 → actions/upload-artifact@v7
  • actions/download-artifact@v4 → actions/download-artifact@v8
