    A duplex stream that runs browserified tape tests with puppeteer.
    Just pipe a browserify stream into this and consume its TAP output.

    Usage:

      browserify [opts] [files] | tape-puppet [opts]

    Options:

      -h, --help\t\tprint usage instructions
      -v, --version\t\tprint version
          --headless\trun chromium in headless mode; default: true
          --devtools\topen devtools; forces !headless; default: false
          --autoclose\tclose chromium when program completes; default: true
          --debug\t\tAdd a breakpoint (debugger) before all code; default: false
          --emulate\t\temulate a mobile device; fx "iPhone X"

          --cover\t\tWrite coverage information to nyc_output.
          --width\t\tchromium window width in px
          --height\t\tchromium window height in px
          --timeout\t\ttimeout for chromium launch in ms; default: 30000
          --wait\t\ttimeout for tap-finished in ms; default: 1000

    Examples:

      browserify ./test.js | tape-puppet
      browserify ./test.js | tape-puppet --devtools
      browserify ./test.js | tape-puppet --headless 0 --emulate "iPhone X"
      browserify ./test.js | tape-puppet > ./test.tap
