Native p5 classes (like p5.Vector) are undefined

[gwezerek]

Describe the bug
Good evening! I've been trying to get some of the p5-sound classes, like p5.Amplitude(), to work with this library. Unfortunately they remain undefined.

I noticed in the closed issues and 3.0 release that there was an attempt to fix the constructor issue. It doesn't seem to be working, based on everything I tried and the repl below.

(Thank you for making this library, btw!)

To Reproduce
See the undefined in the console here:
