Convert TTF files to WOFF2.

This is a NodeJS wrapper for the Google WOFF2 project. If the C++ wrapper compilation fail, it fallbacks to an Emscripten build.

## Usage

Install ttf2woff2 globally, then:

cat font.ttf | ttf2woff2 >> font.woff2

var fs = require('fs');
var ttf2woff2 = require('ttf2woff2');

var input = fs.readFileSync('font.ttf');

fs.writeFileSync('font.woff2', ttf2woff2(input));
