Circular references to Page objects can arise when objects such as annotations refer to their associated page. If these references are not properly handled, the PDF file will contain multiple copies of the same Page object. To address this problem, Page objects store their original object reference number. This method adds the reference number of any circularly referenced Page objects to an external reference map. This ensures that self-referencing trees reference the correct new object location, rather than copying in a new copy of the Page object. Args: root: The root of the PDF object tree to sweep.

If the input indirect object already belongs to this PDF file, it is returned directly. Otherwise, the object is retrieved from the input object's PDF file using the object's ID number and generation number. If the object cannot be found, a warning is logged and a `NullObject` is returned. If the object is not already in this PDF file, it is added to the file's list of objects and assigned a new ID number and generation number of 0. The hash value of the object is then added to the `_idnum_hash` dictionary, with the corresponding `IndirectObject` reference as the value. Args: data: The `IndirectObject` to resolve. Returns: The resolved `IndirectObject` in this PDF file.
