Hi, thanks for creating this.
I tried using Poline in P5, version 2.0.5, but it doesn't seem to work. I also tried to just import it "regularly", eg. something like:

let Poline;
async function setup() {
  ({Poline} = await import('https://unpkg.com/poline?module'))
}

But then I get an Error like this:

TypeError: P.prototype.registerMethod is not a function

Which is most likely because Poline detects P5, but wants to register itself the way it was done in P5 v1.

I think it might be worthwile to check the P5 version (p5.VERSION) and/or wrap the whole p5 initialisation in a try/catch block, so that Poline can still be imported/used as above. What do you think?
