/** This function converts nested entries into a proper tree-like object. When we have single-child directories,

 *
 *
 * { name: "a", ...TreeEntryInfo, children: [
 *     { name: "b", ...TreeEntryInfo, children: [
 *          {name: "c.txt", ...TreeEntryInfo, children: []}

 * It uses the number of '/' separators to determine depth, and recursively adds entries to the `children` field.
