Python bindings report invalid build SDK

LIEF/api/python/MachO/objects/pyBuildVersion.cpp

Lines 93 to 96 in fd8af3a

	.def_property("sdk",
	static_cast<getter_t<BuildVersion::version_t>>(&BuildVersion::minos),
	static_cast<setter_t<BuildVersion::version_t>>(&BuildVersion::minos),
	"SDK Version")

The returned property is BuildVersion::minos but instead BuildVersion::sdk should be returned. This is presumably a copy and paste error.

Here is a simple temporary workaround for anyone who depends on the actual build SDK version:

import lief
import re

from typing import Tuple

def build_version_sdk(binary: lief.MachO.Binary) -> Tuple[int, int, int]:
    rx = re.compile(r'SDK: (\d+)\.(\d+)\.(\d+)')
    m = rx.search(str(binary.build_version))
    return tuple(map(int, m.groups()))

Thanks!
