tslib triggers a process experimental warning in node.js 10.1.0

[mdouglass]

node.js 10.1.0 has moved the experimental version of the fs promises api to require('fs').promises

When tslib imports the fs module it loops over every exported variable which now triggers a process-wide warning which is logged to the console.

(node:78361) ExperimentalWarning: The fs.promises API is experimental

The stack when this happens is:

This seems like a node issue, not a tslib issue. Babel does the same thing for import *.

Looks like it is fixed already by nodejs/node#20632
