Create a strategy for generating Polars DataType objects.

Parameters:
allowed_dtypes

Data types the strategy will pick from. If set to None (default), all supported data types are included.

excluded_dtypes

Data types the strategy will not pick from. This takes priority over data types specified in allowed_dtypes.

allow_time_zones

Allow generating Datetime data types with a time zone.

nesting_level

The complexity of nested data types. If set to 0, nested data types are disabled.
