Remove service worker?

[dbrgn]

The validator contains a service worker: https://github.com/spaceapi-community/validator-web/blob/master/src/serviceWorker.js

This makes it a PWA and provides offline support. However, since we need to call the upstream validator endpoint, offline support is quite useless for us. On the other hand, the service worker adds complexity and potential for subtle caching bugs. (I've fought with buggy cache invalidation in service workers before, and it's not very pleasant.)

I assume the SW is only in there because it's part of some react template. Any reasons not to remove the service worker?
