Use https://omahaproxy.appspot.com/ to find revisions.

Note: The Chromium executable path is exposed to the script as the `CRPATH` environment variable.

If a script is specified, launching Puppeteer from within that script will use the current Chromium revision. Revisions older than 493957 won't work with modern Puppeteer.

This script was extracted from Puppeteer's bisect.js and then cleaned up a bit for public use.
