Fluture v12 Upgrade Guide

Modular version made compatible with Node 12

The modular version of Fluture no longer works with Node version 9, 10, and 11 using --experimental-modules. In order to load the modular version into those runtimes, one has to use the esm loader.

Furthermore, the modular code must now be "deep" imported from fluture/index.js. That is, import 'fluture/index.js' for EcmaScript modules, or require ('fluture') for CommonJS modules.

Future constructor no longer overloaded
