Fix jQuery Migrate issues

[Jamesking56]

Hi! 👋

Firstly, thanks for your work on this project! 🙂

Today I used patch-package to patch jquery-waypoints@2.0.3 for the project I'm working on.

This is because of jQuery Migrate showing a lot of console logs of issues which need to be fixed because of jQuery planning to remove functions.

Here is the diff that solved my problem:
