As said on #170, i added the support for the old format used by https://github.com/hyj1991/v8-profiler-node8 (which is currently used for pm2.io).
This adds support for importing heap profiles from Chrome: https://developers.google.com/web/tools/chrome-devtools/memory-problems/#allocation-profile
This is inspired by https://github.com/mapbox/flamebearer
