[Export Rendered View] Exports the WYSIWYG version of a certain region as a jpeg with a metadata field appended to the image name. Works with Run for Project #qupath

// Export Rendered view of S1HL as open in QuPath with metadata tag  in file name

// NOTE: Make sure that all settings are as you want them on a currently open image (Channels, hidden Pathclasses, Annotation names, ...) before you start, as your current display and layer settings will be applied to all image if you use "Run for Project"
