Node.js bindings of otfcc?

[chengluyu]

Any idea to make otfcc a Node.js binding? For example:

const otfcc = require('otfcc');
const data = otfcc.dumpFromFile('font.ttf');
// do something
otfcc.buildFromJSON(data, { optimizeLevel: 3, ignoreHints: true });

Currently I'm using child_process to manually invoke otfcc, which is really a pain.

I am not very familiar with creating C++ modules... though there is a DLL target in the current code. Windows build requires VS2017 and Clang -- but you can use prebuilt DLLs.

PRs are welcome (please push to the poly branch).
