Allow compression of url

I've found some examples hit the "URI too long" warning on safari.
Compressing the URL could help with this:

• http://nodeca.github.io/pako/
• https://pieroxy.net/blog/pages/lz-string/index.html

Did a rough check with pako (picked at random) and a large set of txs + a query was compressed to ~10% of it's original size.
Roughly what I expected so definitely worth it for at least working with design partners.
