Does not work on the Nano 33 IOT

[DarkKaplah]

This works great for my Uno, standard Nano, and Mega Arduinos. Trying this on a nano 33 iot and it results in a string of 1's on the seral terminal. Hitting a key results in a response of the first column of that row (if I hit 5 I get a 4, a 0 gets a *, etc). There is a note that libraries need to be updated for the nano 33 iot in the forums. Will this library be updated or is there a suggested replacement?
