cli would be faster if it was bundled in one file

[gre]

a quick analysis running node --cpu-prof --heap-prof cli/lib/cli.js sync shows that module loading takes roughtly 1s, maybe because fs/require time.

We could try https://github.com/zeit/ncc 🤔

[gre]

seems like we can gain 1s yeah. it's probably worth having it in prepublish script then and change the entry point to that dist (and ultimately cli.js can be dropped).

[gre]

ok this was not accurate. we're more on a 40% gain. still good.
