const data = await res.arrayBuffer()
const sizeInfo = sizer(data)
console.log(sizeInfo); // =>
/*
  {
    width: xx,
    height: yy,
    type: 'jpg',
    mime: 'image/jpeg',
    wUnits: 'px',

// If you know the type of image you can run sizer with an extension
let sizeInfo = sizer(data, 'jpg')
console.log(sizeInfo); // =>
