global_platform: install_cap_parser: argument groups cannot be nested
pySim-shell currently does not work on systems with Python 3.14+:
File ".../pysim/pySim/global_platform/__init__.py", line 868, in AddlShellCommands install_cap_parser_inst_prm_g_grp = install_cap_parser_inst_prm_g.add_argument_group() File "/usr/lib/python3.14/argparse.py", line 1794, in add_argument_group raise ValueError('argument groups cannot be nested') ValueError('argument groups cannot be nested')
The problem is that install_cap_parser creates a nested group inside of mutually exclusive group. argparse never supported group nesting properly, so it has been deprecated since Python 3.11, and eventually got removed in Python 3.14.
Remove group nesting, adjust the usage string, and implement the mutual exclusiveness/inclusiveness manually in do_install_cap().
