    A fork of JSZip that aligns all files in generated ZIPs to 64 bits of the start, so that they can be accessed directly with mmap

    The purpose is to ensure that all uncompressed data starts with a particular alignment relative to the start of the file. This allows those portions to be accessed directly with mmap() even if they contain binary data with alignment restrictions. Some data needs to be word-aligned for easy access, others might benefit from being page-aligned. The adjustment is made by altering the size of the "extra" field in the zip Local File Header sections. Existing data in the "extra" fields may be altered by this process.

    var zip = new JSZip();
    
    zip.file("Hello.txt", "Hello World\n");
    
    var img = zip.folder("images");
    img.file("smile.gif", imgData, {base64: true});
    
    zip.generateAsync({type:"blob"}).then(function(content) {
        // see FileSaver.js
        saveAs(content, "example.zip");
    });
