Support for passing carriers as a list in InstructionToSignals.
The Solver.signals property, and the Solver init kwargs hamiltonian_signals and lindblad_signals.
Associated with this, the Solver.solve method has been updated to always reset the Solver.model signals to None.
The Solver.copy method has been removed.
Tests that checked for the deprecation warnings have been removed. I've added a test that verifies that the Solver.model.signals property is always returned to None (or (None, None) for a Lindblad model) after calling Solver.solve.
