No binding for SelectMgr_IndexedMapOfOwner type

Calling method [EntityOwners](https://dev.opencascade.org/doc/occt-7.6.0/refman/html/class_a_i_s___interactive_context.html#a8cb62d753221eabc4b04f53585c1085f) of AIS_InteractiveContext requires data type [SelectMgr_IndexedMapOfOwner](https://dev.opencascade.org/doc/occt-7.6.0/refman/html/_select_mgr___indexed_map_of_owner_8hxx.html#a876693f57b4083b0db2e744396ca708f) which seems to be missing in module SelectMgr of OCP. Calling the function contains the following report:
```
TypeError: EntityOwners(): incompatible function arguments. The following argument types are supported:
1. (self: OCP.AIS.AIS_InteractiveContext, theOwners: NCollection_Shared,NCollection_DefaultHasher > >,void>, theIObj: OCP.AIS.AIS_InteractiveObject, theMode: int = -1) -> Tuple[]
```
I guess the annotation for argument `theOwners` is an additional indication that the underlying C++ type is not associated with any Python type. I wonder if it would be possible to enable this method in OCP.
