Fix ImageStatsTool not working with XYImageItem and MaskedXYImageItem

Add IExportROIImageItemType to XYImageItem.types() so that
get_items_in_rectangle() can find XY image items when filtering
by interface type. Also update __implements__ tuples for consistency.

Fixes regression where ImageStatsTool displayed "No available data"
instead of statistics for images with non-uniform coordinates.

+
+🛠️ Bug fixes:
+
+* [Issue #50](https://github.com/PlotPyStack/PlotPy/issues/50) - Fixed ImageStatsTool displaying "No available data" for `XYImageItem` and `MaskedXYImageItem`:
+  * Added `IExportROIImageItemType` to `XYImageItem.types()` so that `get_items_in_rectangle()` can properly identify XY image items
+  * Updated `__implements__` tuples for consistency across `XYImageItem`, `MaskedXYImageItem`, and `MaskedImageItem`
+  * The tool now correctly displays statistics for images with non-uniform coordinates
