Upgrade to Latest Node Versions

[winrid]

It seems based on discussions in the Screeps discord the engine is not compatible with latest Node versions. It sounds like the infra is on Node 8 today? @o4kapuk is there any interest in upgrading the engine/infra to improve tick times? I can create the PR if devs want to actually do the upgrade...

We certainly plan to upgrade nodejs on production although we don't expect it to improve tick times

its been over a year - are there still plans to upgrade beyond Node 8? Even systems that would be considered out of date are using Node > 8 now and it makes using existing development starters a pain as npm bin was dropped in Node 9+ [1]
