 * Recursively processes a nested JavaScript object, replacing Base64-encoded

 *
 * This function iterates through all properties of the input object (and
 * recursively through any nested objects).  If it finds a string value that
 * starts with the prefix `'__ipecharts_jsfn__::'`, it assumes the rest of the
 * string is a Base64-encoded JSON representation of the function's arguments
 * and body. It then decodes the string, parses the JSON, and creates a new
 * function using the `Function` constructor, replacing the original string
 * with the created function.
