Update the project page of the precursor module, Elevate Image Zoom

In fact, these 2 modules use 2 different methods and 2 different libraries
Image elevate zoom plus → uses CDN
https://github.com/igorlino/elevatezoom-plus (last update 2020 - more effects)
and another one uses old library Image elevate zoom (no cdn, and have to download to libraries offline, stop support since 2012)
use as your need.

base on module Elevate Image Zoom
but this module is no longer under maintenance and too many errors, I decided to redo it all with new library jQuery ElevateZoom Plus Plugin

The above message on the project page suggests one should not use the other module if starting a new project.
