Issue 1609 (#1613)

* Fixed issue #1609 (Cell.read doesn't read LayoutMetaInfo)

This also includes some more functions:
- Layout#merge_meta_info, Layout#copy_meta_info
- Layout#clear_all_meta_info
- Cell#merge_meta_info, Cell#copy_meta_info

In addition, meta info is merged when importing a layout from
another file (Layout/Import -> Other Layouts into current).

* Meta info support in layout diff (for testing), implemented meta info merge for GDS and OASIS readers with special conflict resolution modes

* Undo support for meta info - this way we do not loose meta info when we delete a cell and undo
