Disassemble in Extended not stopping at function boundary

[palmerc]

Describe the bug
When disassembling a function in LIEF extended the returned iterator does not stop at the function boundary

To Reproduce

def get_function_disassembly(binary_name: str, function_name: str) -> str:
    fat_macho = lief.MachO.parse(binary_name)
    thin_macho = fat_macho.take(lief.MachO.Header.CPU_TYPE.ARM64)
    instructions = thin_macho.disassemble(function_name)
    for instruction in instructions:
        print(instruction)

get_function_disassembly('/path/to/binary', 'function_somwhere_near_the_top')

Expected behavior
Ideally, some sort of block analysis that returns only the instructions pertinent to the named function not the entire subsequent disassembly.

Environment (please complete the following information):

• System and Version : macOS Sequoia
• Target format Mach-O
• LIEF commit version: 0.17.0-

My workaround for this was to use lldb, but a pity you can't stay within LIEF

def get_function_disassembly(binary_name: str, function_name: str) -> str:
    cmds = ['lldb', '--arch', 'arm64', '--batch', '-o', f'disassemble -n {function_name}', '--file', binary_name]
    try:
        return subprocess.check_output(cmds).decode('utf-8')
    except subprocess.CalledProcessError:
        return ''
