Feature suggestion: debounce url updating

[neeasade]

I'm a serial highlighter when reading text on the internet. I like to use the mouse and click/drag things as I go, and deeplinks.js as-is can slow down that interactive reading experience a little bit. Around a year ago, I forked linktext.js and added a delay to setting the url, removing the lag feeling when highlighting text on the site (you can see in action here). Making the issue so it can be considered over here as well.
