Add a new transform table column backed by a Foundry function. The new column can be of type boolean, string, number, or time, depending on the output of the function.
To use a function in this transform, it must satisfy the following requirements:
The function input parameters must include an ObjectSet<ObjectType> parameter (and can optionally include other input parameters).
The function return type must be a FunctionsMap<ObjectType, CustomType>.
The FunctionsMap keys are objects with object IDs matching those in the table.
