Cannot get __Text segment from a MachO object file

[xiangqianli]

Describe the bug
I have a .o file generated within a .a MachO static library, with lief, I cannot get __Text segment from object file, while with MachoView the .o file's __Text segment is clear.

but with lief I can get __Text segment from an executable file, does lief not support this ability from object file?

To Reproduce
Steps to reproduce the behavior:
In Python:

if name == 'main':

fatbinary = lief.MachO.parse("./XQPerson.o", config=lief.MachO.ParserConfig.deep)
binary = lief.MachO.FatBinary.take(fatbinary, lief.MachO.CPU_TYPES.ARM64)
print_segments(binary)
print(binary.get_segment("__TEXT"))

Console Result:

Expected behavior
Get the __Text segment from .o MachO Object file correctly
