Fixes deprecated use of np.float, np.int, etc.

Switch from dill to cloudpickle for saving/loading Study-objects to/from file. This ensures compatibility with JupyterLite as dill cannot easily be imported in a pyodide kernel.

Fix deprecated import from collections to ensure compatibility with Python 3.10.

• Fix saving/loading models
• Fix initialization of backwards pass
• Fix tests

Re-release because of broken wheel file.

Re-release due to pypi version conflicts.

Fixes:

• restore description on pypi

New features:
