/// # Destination Creation
///
/// Unlike [`Extractor::new`], this function creates the destination directory if
/// it doesn't exist. This is convenient but means typos like `/var/uplaods` will

/// # Example
///
/// ```no_run
/// use std::io::Cursor;
/// use safe_unzip::extract;
///
/// let zip_bytes = std::fs::read("archive.zip")?;
/// let report = extract("/var/uploads", Cursor::new(zip_bytes))?;
