A little bug in ezdxf/explode.py

[IvanKachaikinCendas]

In ezdxf/explode.py, line 247, the function virtual_block_reference_entities is called in an incorrect way that throws an exception if ever ezdxf goes there.

More specifically, the function definition is:

def virtual_block_reference_entities(
    block_ref: "Insert",
    *,
    skipped_entity_callback: Optional[
        Callable[["DXFGraphic", str], None]
    ] = None,
    redraw_order=False,
) -> Iterable["DXFGraphic"]:
  pass

But the call is something like virtual_block_reference_entities(entity, skipped_entity_callback) that essentially throws an exception. For me the following call instead fixed the problem, and I think it should be the same at the point that I refer to:

virtual_block_reference_entities(entity, skipped_entity_callback=skipped_entity_callback)

Thanks in advance for taking this issue into account! :)

P.S.: sorry, cannot share with you the DXF to reproduce because it is private, thanks for your understanding!
