Pixel-perfect mask annotations in V7

You can now use V7 to create semantic masks. This new class type allows you to create pixel-perfect labels and determine the identity of individual pixels, which is essential for semantic segmentation tasks.

Your masks will appear as a separate layer. You can also add other types of annotations, such as polygons, on top of your semantic masks. Combining different classes and attributes with your masks may be useful if your use case requires panoptic segmentation.

Additionally, the update supports exporting masks in the Darwin JSON format, ensuring compatibility and ease of use in various workflows.
