Research: Image loading performance optimization

[masonmcelvain]

We need to make this app more performant in terms of image loading and video playback.

• We could use image compression to keep file sizes small.
• We could use cacheing of places already visited to make fewer requests to get image/location data from the API.
• Progressive loading of images (low quality if on first load, replaced by high quality if not on mobile).

Take away from above and other sources:

• WebP files are ~30% smaller but maintain roughly the same quality
• Not supported by Safari
• Supported by most other browsers though

AVIF is another file compression format with great compression (about 50% smaller file sizes than JPG). Doesn't have as much browser support as WebP however.
