[Win32]Memory View Hex Editor Issue

[YingHuoChong4913]

I found that since version 2.3 of fceux, due to the change of the pasting method, the original batch writing data has been changed to circular writing data, and different pasting methods have also been distinguished. Although this is possible, why can only execute the undo method once when undoing it? Why not make a circular batch undo like insert? And I also found that only the editing of Rom files can be undone, and other modes cannot be undone. I don't know why, but I feel that it is really inconvenient. Hope the official can fix this problem. I think memview.cpp really needs to be redesigned for undo. The paste design is okay, but the undo also needs to be removed, right? Hope to be aware of this problem and fix it.
