add new element into cells or cells_dict

[yjhp1016]

Hi, I'm trying to add new element into cells, but a little bit confused about which one I need to adding into:meshio.cells or meshio.cells_dict.

For my case, I seems to me that the structure of cells_dict is more friendly, so can I adding new components into cells_dict only? Is there some function to automatically update data in cells?

Thanks!
