docs: Remove previously stored attributes from this plugin instance to save memory.
          This method is supposed to be called by breakpoint implementors. A typical workflow looks like the following :
  
          >>> # Add `attr0` and `attr1` to `self.state.inspect`
          >>> self.state.inspect(xxxxxx, attr0=yyyy, attr1=zzzz)
          >>> # Get new attributes out of SimInspect in case they are modified by the user
          >>> new_attr0 = self.state._inspect.attr0
          >>> new_attr1 = self.state._inspect.attr1
          >>> # Remove them from SimInspect
          >>> self.state._inspect.downsize()
