Web based large image support

[BryonLewis]

Support for displaying and annotating large images in DIVE on the web.

Will require:

• [x] 1. Getting girder-large-image plugin and installed and properly configured
• [x] 2. Capability to upload a large image file formats to the web through the UI and prevent filtering them out on the backend
• [x] 3. Ensure that large TIFS or pyramidal Tifs are no longer converted and are viewed using large image. For now consider large to be any tiff with a dimension >8k
• [x] 4. Allowing large images to be displayed as a new dataset type along side image-list and video. This means that the correct dataset is returned.
• [x] 5. Requesting dive_dataet/media endpoint will return a large image url to be used for displaying purposes.
• [x] 6. We currently have two MediaAnnotators, ImageAnnotator and VideoAnnator. A third one needs to be made LargeImageAnnotator which will use the proper geoJS displaying for large images.
• [x] 7. Keep everything edited in pixel space for now.
• [ ] 8. Update the exporting options so it can download large image files
