General sampling estimator

[dchung0741]

Directly provide general sampling estimator to users via the new create_general_sampling_estimator function. The input parameters are exactly the same as those that creates a (concurrent_)sampling_estimator.

Example code:

general_sampling_estimator = create_general_sampling_estimator(
    total_shots,
    sampler,
    bitwise_commuting_pauli_measurement,
    allocator,
)


# estimator
general_sampling_estimator(op, state)

# concurrent estimator
general_sampling_estimator(op, [state_1, state_2])
general_sampling_estimator([op], [state_1, state_2])
general_sampling_estimator([op_1, op_2], state)
general_sampling_estimator([op_1, op_2], [state])
general_sampling_estimator([op_1, op_2], [state_1, state_2])

# parametric estimator
general_sampling_estimator(op, param_state, param)

# parametric concurrent estimator
general_sampling_estimator(op, param_state, [param_1, param_2])
