[FIX] #39: mkdir cross-platform on macOS

Replaced all plumbum.cmd.mkdir invocations that used GNU-style long-option forms for --mode and --parents with single-character flags (-m and -p).

MacOS mkdir doesn’t support --mode or --parents in GNU-style long-option form. These work on GNU/Linux (Debian, Ubuntu, etc.), but macOS uses BSD-style utilities, where options are single-character flags like -p and -m (which also work on GNU/Linux).
