tapered binary fix int typing

[JdelArco98]

on openfermion/transforms/opconversions/binary_code_transform.py line 163 it breaks (with numpy>2.) because (-1) ** updated_parity being updated_parity numpy.count_nonzero(fermionic_indices[:op_idx] < op_tuple[0]) line 146 (therefore a numpy.int) is not instance of int, as it is checked on openfermion/ops/operators/symbolic_operator.py line 124

Code Review

This pull request modifies the binary_code_transform function in binary_code_transform.py to cast updated_parity to an integer when calculating the parity sign exponent, preventing potential type-related issues. There are no review comments, so I have no feedback to provide.
