Feature or enhancement

Proposal:

Currently there is no way to determine the sign of the PyLongObject value and CPython extensions use private macroses like _PyLong_IsNegative(): https://github.com/aleaxit/gmpy/blob/eb8dfcbd84abcfcb36b4adcb0d5c6d050731dd75/src/gmpy2_convert_gmp.c#L56

PyLong_Sign() will offer GMP-like API to do this.

This was suggested before: #102471 (comment)

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere
