Enable annotations (drawing on the map)

[WUOTE]

The annotations plugin is already added to the project but has not been activated.

noitamap/public/js/script.js

Lines 857 to 859 in 00df676

	// const annotations = new OpenSeadragon.Annotations({ viewer });
	// os.initializeAnnotations();

Current issues are:

• The pugin puts its controls at the very bottom left of the map container making it almost impossible to use.
• There are no means of sharing an annotation (similar to copying current zoom level and coordinates to the clipboard).
