__len__

Expose len on IntervalSets

Bugfix to 0.3

Actually expose the new filter_to_overlapping_and_split API

Expose new nested_intervals functionality

Nested intervals now can filter & cut the filtered
intervals down to the actual regions overlapping in the target.

This release introduces this, and other missing pieces to the python wrapper.

Updated pyo3

Upgraded pyo3 to newest version.

v.2.10

• correctly filter for negative or empty intervals, just like nested_intervals does it
• pandas drift fixed
