Allow removeEventListener in listener callback

[Kal-Aster]

Having a callback with a call to removeEventListener on the same EventTarget causes the listeners list to change hence to skip some listener.

Here an example

const { EventTarget, Event } = require("basichtml");

const e = new EventTarget();
e.addEventListener("test", function test() {
  e.removeEventListener("test", test);
  console.log("test 1");
});
e.addEventListener("test", function test() {
  // this never runs because of the `removeEventListener` in previous call
  console.log("test 2");
});
e.addEventListener("test", function test() {
  // this runs because the iterator kept going
  console.log("test 3");
});
e.dispatchEvent(new Event("test"));

The change is small and sensible enough, this module has been deprecated and (I think) archived? I suggest you to move to LinkeDOM ASAP, as I’m not maintaining this module these days, and quirks are known and many.

actually, I haven't deprecated this ... will do soon.
