Function convert_workbook_with_options 

pub fn convert_workbook_with_options(
    from: Format,
    to: Format,
    input: &[u8],
    dialect: SqlDialect,
    table_name: Option<&str>,
) -> Result<Vec<OutputDoc>, Box<dyn Error>>

Like convert_workbook, but lets the caller pick the SQL dialect and the table name used when writing SQL output.
