/// Asserts that two DataFrames are equal according to the specified options.
///
/// This macro compares two Polars DataFrame objects and panics with a detailed error message if they are not equal.
/// It provides two forms:
/// - With custom comparison options
/// - With default comparison options
///
/// # Example
///
/// ```
/// use polars_core::prelude::*;
/// use polars_testing::assert_dataframe_equal;
/// use polars_testing::asserts::DataFrameEqualOptions;
///
/// // Create two DataFrames to compare
/// let df1 = df! {
///     "a" => [1, 2, 3],
///     "b" => [4.0, 5.0, 6.0],
/// }.unwrap();
/// let df2 = df! {
///     "a" => [1,
