Usage

1. Compress Image

const { compressImage } = require('./index');

const result = await compressImage({
  input: './image.jpg',
  quality: 80,
  output: './compressed.jpg'
});

const result = await upscaleImage({
  input: './image.jpg',
  scale: 2,
  output: './upscaled.jpg'
});

// Or specify exact dimensions
const result = await upscaleImage({
