New features

Pylbo

• Introduction of optional argument display_info in the load and load_series functions to turn of writing datfile information to terminal.
• Keypress function _save_eigenvalue_selection to save interactively selected eigenvalues and their eigenfunctions to a .npy file.
• Keypress function _save_selection_indices to save the indices of interactively selected eigenvalues to a .npy file.

Checklist

• all tests pass (and for new features, new tests are added)
• documentation has been updated (if applicable)
