Issue 1547 large image conversion

[BryonLewis]

resolves #1547

Large images don't decode properly and provide a image width/height. If this occurs for a regular image I think it should ask the user to kick off a convert to large image task.

• Modified the code so that if it can't decode the image it will suggest conversion to a large image
• Inside the large image conversion we need to check and see if the items has already been converted before we convert it to a large image
• When you open a dataset that isn't loading/decoding properly it will prompt the user to swap it to a 'large-image' dataset.
• This conversion job will launch and on completion it will ask to reload the annotations and will display the materials.

Sample Data:
LargeSampleImages.zip

Note:
You may need to build the whole image and use (localhost:8010) so the notification system is properly connected for the indicator to ask to reload after conversion.
