 * Hashes each file in each directory, and then hashes the hashes to create a hash for each directory also.
 *
 * Whilst files are hashed in their entirety, the logic for creating a folder hash is as follows:
 *
 * Sort the files and subfolders by name (case sensitive, uppercase then lower)
 * Take the first 100 hashes, concatenate and hash
 * Concatenate this hash with another 100 hashes and hash again
 * Continue until the end of the folder. This is the folder hash
 * If a folder contains other folders, start from the bottom of the tree - the folder hashes cascade upwards so you know immediately if there is a change in a sub/sub directory
 * If the folder has no content (empty) then it is ignored. No hash created.
 *
 * @param {string} folderPath - absolute folder path
