Add early validation of the --saveEngine output path to fail fast when the path is invalid or unwritable, avoiding wasted computation. This change adds a canWriteFile() utility function that: - Checks if the parent directory exists - Tests write permissions by creating a temporary file - Cleans up the temporary file after testing The validation runs immediately when --saveEngine is parsed, before any expensive ONNX parsing or engine building operations.
