Migrate pmoutils to registry and refactor dependencies

Migrate pmoutils crate to registry version 0.1.2 and update all dependencies to use the registry version instead of local path references. Remove pmoutils from Cargo.lock and Cargo.toml files where it was previously used as a local path dependency. Move ToXmlElement trait to pmodidl crate and update all usages to import from pmodidl instead of pmoutils. Fix parameter order in find_process_using_port function call.
