v1.0.3

This is a bug-fix only release. All users on 1.0.x are recommended to upgrade to this version.

Bug fixes:

• Major performance and memory use improvements, especially when using intersections = 'all'
• The max_combinations_n fail-safe was replaced by a more useful max_combinations_datapoints_n with more precise error message
• The atypical use case of filtering with max_degree = 0 is now accepted again
• Fix tests using all the data (effectively union mode) rather than chosen mode data only
