Reliably decide whether a predicate is an AP or OP

[matentzn]

To be able to render an OWL existential restriction correctly from SSSOM, we need to be able to infer whether a predicate is an AP or OP.

• 👍 One idea would be to assume AP, and add an optional predicate_type column to SSSOM from which this information can be obtained.
• 🚀 Alternatively, we can create a dictionary at release time that contains the types (using OMO/RO as input) - this is less flexible (no way add custom mappings).
• 👀 Last but not least we can add a new parameter to convert that takes a type dictionary as input.

Does biolink has a curated table like this that keeps the types of some known properties?
