Add Support for Lottie .json resources

[chrismessina]

Is your feature request related to a problem? Please describe.
In addition to static SVG resources, sites are increasingly adding Lottie animations to their repertoires.

SVG Grabber might expand its mandate to include all assets (i.e. become "Asset Grabber").

Describe the solution you'd like
For Lottie .json files, there could be a new tab for animated resources. When you hover over a resource, it could show a preview of the animation.

Describe alternatives you've considered
Manually downloading each resource from the Developer Tools UI.

Additional context
It appears that you could use the Lottie Wrapper for React on the web to possibly render these animations in the Chrome Extension.

You may be able to detect Lottie animations by looking for the .lottie-container class, for example on this page.
