Downloads an image. While the only required query parameters are collection name, imagery type name, and image type name, you must provide enough additional information to identify a single imagery in the collection that contains the desired image through one of the following methods:
a) the imagery's name, using the 'name' query parameter, if it's name is unique,
b) the imagery's depth interval, using the 'startDepth' and optionally 'endDepth' query parameters, or
c) the imagery's unique id, using the 'imageryId' query parameter.
If the collection name is not unique within your subscription, you may also need to provide datasetName and workspaceName to uniquely target it.
