Implement responsive images for performance #38

This should allow us to balance load on IIIF server vs. delivering images close to the user's window size. See Responsive images on MDN for more info.

Recommended sizes to maximize likelihood of hitting an existing cache: 200, 400, 843.

Less likely, but also possible: 600, 1280, 1686.

@IllyaMoskvin will try a different approach for fullscreen images using openseadragon

Implemented in c0967f8 using OpenSeadragon's "legacy image pyramid" Tile Source.
