NOTICE:
 * Before running composer command, make sure you have the composer version updated.

STEPS:
 * Create a temporary folder outside your moodle installation
 * Create a composer.json file with the following content (you will need to replace X.YY to the proper version to be upgraded):
{
    "require": {
        "phpoffice/phpspreadsheet": "^X.YY"
    },
    "replace": {
        "ezyang/htmlpurifier": "*",
        "maennchen/zipstream-php": "*",
        "myclabs/php-enum": "*",
        "symfony/polyfill-mbstring": "*"
    }

   - /vendor/ezyang/htmlpurifier
   - /vendor/maennchen/*
   - /vendor/myclabs/*
   - /vendor/symfony/polyfill-mbstring
 * If it has pulled these through, remove them from the required packages and run composer again.

 * If the following exist, remove the following folders (and their content):
   - vendor/phpoffice/phpspreadsheet/bin

 * Remove the old 'vendor' directory in lib/phpspreadsheet/
 * Copy contents of 'vendor' directory
 * Create a commit with only the library changes
 * Update lib/thirdpartylibs.xml
 * Apply the modifications described in the CHANGES section
 * Create another commit with the previous two steps of changes
 * Go to http://<your moodle root>/lib/tests/other/spreadsheettestpage.php and test the generated files


CHANGES:

 * Add the next Moodle hack at the beginning of the function sysGetTempDir()
located in lib/phpspreadsheet/vendor/phpoffice/phpspreadsheet/src/PhpSpreadsheet/Shared/File.php
    // Moodle hack!
     if (function_exists('make_temp_directory')) {
         $temp = make_temp_directory('phpspreadsheet');
         return realpath(dirname($temp));
     }
  This hack is needed because it can not be guaranteed that sysGetTempDir() works everywhere.
