Interface Changes

1. Python SDK:
   • Change interface of QVar:
     • QVar type-hints now expect a quantum type, which is a subclass of QVar.
     • The main types are QBit (a single qubit type) and QArray[QBit] (an array of qubits).
     • See Basic Functions for details.
   • Support arithmetic quantum types. See Quantum Types and Expressions for details.
2. Remove the simplify option from Arithmetic and ArithmeticOracle. It will now be done automatically.
