CommandLine: not well-handle all input parameters

[ZDu-IDM]

def __init__(self, executable=None, *args, is_windows: bool = False, raw_args: List[Any] = None, **kwargs):

Consider the case:

cmd_str = "singularity exec Assets/my_sif.sif Assets/my_executable --config my_config.json"
command = CommandLine(cmd_str, '--dll-path',  './Assets', raw_args=['--input-path', './Assets\;.'])
command.add_option("--python-script-path", 'dtk_post_process.pyn;dtk_pre_process.py')

and

cmd_str = "singularity exec Assets/my_sif.sif Assets/my_executable"
command = CommandLine(cmd_str, '--dll-path',  './Assets', raw_args=['--input-path', './Assets\;.'], kwargs={"--config":"my_config.json"})
command.add_option("--python-script-path", 'dtk_post_process.pyn;dtk_pre_process.py')

Check result:
print(command.cmd)
