Feature Request: Support for Multilayer Hypergraphs with Heterogeneous Layer Types (Directed & Undirected) #71

I would like to propose adding support for multilayer hypergraphs with heterogeneous layer types, where different layers can independently support directed and undirected hyperedges.

Dependency on Existing Work

This feature builds upon and depends on issue #47, which requests support for directed hypergraphs.
Since heterogeneous multilayer hypergraphs require some layers to be directed, implementing #47 is a necessary prerequisite before this feature can be fully realized.
