Allow delete logic to be specified using predicate syntax

[fjetter]

We currently only support the deprecated query syntax for deletion scopes. It would be more intuitive to specify the deletion scope using the predicate syntax.

Old syntax

update_dataset_from_ddf(
    new_ddf,
    ...,
    delete_scope=[
        {
            "index_col": 1,
        },
        {
            "index_col": 2,
        },
        {
            "index_col": 3,
        }
    ]
)

New syntax

update_dataset_from_ddf(
    new_ddf,
    ...,
    delete=[[
        ("index_col", ">=", 1),
        ("index_col", "<=", 3),
    ]]
)

This new implementation would also allow us to better define the semantics for scenarios where an index doesn't exist (which currently doesn't raise) or a secondary index is used (which currently may raise under certain circumstances)
