V0.1.0

This is the first release for the qcir_sim library focussing on simplifying the quantum circuit simulations and benchmarking for small use cases.

Currently, it contains a few examples to demonstrate the usage of the library:

1. Benchmarking how many qubits can we simulate using Vector and Tensor simulation
2. Sampling the Qubits from a Quantum simulation
3. Calculating the expectation values of <Ψ| Op |Ψ>
