/// A macro to check the result of an OCR call and return an error if it fails.
/// This macro takes an expression `$call` and an error message `$err_msg`.
/// If the result of `$call` is not 0, it returns an `OneOcrError::OcrApiError` error with the provided message.
/// This macro is used to simplify error handling in the OCR engine methods.
/// It helps to avoid repetitive error checking code and makes the code cleaner and more readable.
