Cant save images that marked as an placeholder with an object instead of a picture, and the solution

[alenwesker]

As the title, I also turn the fix of the previous issue "cant save wmf" into a patch. I fixed it. Since I am busy working on something, pardon me for not making it a formal patch quest.

The key fix is in parser.py:

      elif shape.shape_type == MSO_SHAPE_TYPE.PICTURE:
        notes += process_picture(shape, idx + 1)
      elif shape.shape_type == MSO_SHAPE_TYPE.TABLE:
        notes += process_table(shape, idx + 1)
      else:  # Add the following lines
        if hasattr(shape, "placeholder_format"):
          ph = shape.placeholder_format
          if ph.type == PP_PLACEHOLDER.OBJECT and hasattr(shape, "image") and getattr(shape, "image"):
            notes += process_picture(shape, idx + 1)
          else:
            print(f"Unrecognized shape: {shape.shape_type}, place holder: {ph.type}, place at page: {idx + 1}")
        else:
          print(f"Unrecognized shape: {shape.shape_type}, place at page: {idx + 1}")
