Don't track hits when running on localhost

[wheresalice]

When I'm doing local development on a website which uses bearlytics, my traffic still gets counted.

I would like script.js to be aware that it is being called from a page served from localhost and not sent the fetch to bearlytics in that case.

That seems easy enough to do, but maybe people would want this to be configurable. At which point I'm not clear on the best approach of achieving this.
