Fails to build with cython 3.1

Currently vidcutter fails to build on Arch Linux with cython 3.1.3:

Error compiling Cython file:

    elif isinstance(obj, int) or isinstance(obj, long) and obj:

It seems that removing the or isinstance(obj, long) part at

vidcutter/vidcutter/libs/pympv/mpv.pyx

Line 811 in db6818f

elif isinstance(obj, int) or isinstance(obj, long) and obj:

fixes the build.
