feat: migrate to picoquery

[43081j]

Migrates away from qs to picoquery, a much lighter (594K vs 41K) and faster alternative.

I actually made this branch to prove out picoquery during development, so if you'd rather stick with the existing dependencies, just let me know and we can close this PR.

While I am (currently) maintainer of picoquery, its part of a wider effort to contribute to performance changes across the ecosystem (see here for example). In this case, reducing the twilio library's package size and increasing speed.
