With 64bit python, result of G722.decode() is broken.

[ynkdir]

With 64bit python (3.12.4 amd64), result of G722.decode() is broken.

Reproducible code:

from G722 import G722

while True:
    arr = G722(16000, 64000).decode(b"00")
    print(len(arr))
    assert len(arr) == 4

Result:

PS C:\Users\yukih\Downloads\libg722> .\venv\Scripts\python.exe .\test.py
4   <- expected
140728898420740   <- invalid length
Traceback (most recent call last):
  File "C:\Users\yukih\Downloads\libg722\test.py", line 6, in <module>
    assert len(arr) == 4
           ^^^^^^^^^^^^^
AssertionError

This is caused by sizeof(long) (4) != sizeof(np_intp) (8).

I forgot to mention that I'm using Windows.

@ynkdir would it be possible for you to create a unit test? I have added some minimal build/test on Windows recently. See test.py & .github/workflows/build_and_test.yml. Thanks!

I've fixed the issue, added unit test and rolled a new release 1.2.0. Thanks for reporting!

Thank you.
