Convert TTF files to WOFF2 ones.

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

Install ttf2woff2 globally, then:

cat font.ttf | ttf2woff2 > font.woff2

On Windows without cat, use (in PowerShell):

Start-Process -NoNewWindow -Wait ttf2woff2.cmd -RedirectStandardInput font.ttf -RedirectStandardOutput font.woff2
# OR
start-process -nnw -wait ttf2woff2.cmd -rsi font.ttf -rso font.woff2

import { readFile, writeFile } from 'node:fs/promises';
import ttf2woff2 from 'ttf2woff2';

const input = await readFile('font.ttf');

await writeFile('font.woff2', ttf2woff2(input));

To build the binary, clone the repository and run the following:

## Setup (works for Ubuntu/Linux, may be different on other OS)
apt-get install make g++

## Actual build
npm i
npm run configure
npm run make

To build the Emscripten fallback, install Emscripten and run:

npm run emcc

Finally the build can be tested:

npm run build
npm t
