Add accessor for `Binary` in engine_data

[Fokko]

Please describe why this is necessary.

It implements a couple of methods today, but I think it would be good to add binary as well 👍

delta-kernel-rs/kernel/src/engine_data.rs

Lines 164 to 178 in f431de0

	/// When calling back into a [`RowVisitor`], the engine needs to provide a slice of items that
	/// implement this trait. This allows type_safe extraction from the raw data by the kernel. By
	/// default all these methods will return an `Error` that an incorrect type has been asked
	/// for. Therefore, for each "data container" an Engine has, it is only necessary to implement the
	/// `get_x` method for the type it holds.
	pub trait GetData<'a> {
	impl_default_get!(
	(get_bool, bool),
	(get_int, i32),
	(get_long, i64),
	(get_str, &'a str),
	(get_list, ListItem<'a>),
	(get_map, MapItem<'a>)
	);
	}

Describe the functionality you are proposing.
