Do you consider implementing `Maybe#orElse()` method?

Hi, thanks for the lib. Love it! ❤️

Do you find Maybe#orElse() method useful and consider implementing it? I find it useful in order to gracefully avoid such constructions:

let maybeGTINs = getGTINsFromString(string);
if (maybeGTINs.isNone()) {
  let maybeGTINs = just(['default']);
}

with something like this:

const maybeGTINs = getGTINsFromString(string).orElse(['default']);

Monet’s seem to have one, but it accepts a Maybe instance for some reason. I guess, the best implementation would be the one mentioned in this article: https://jrsinclair.com/articles/2016/marvellously-mysterious-javascript-maybe-monad/

Maybe.prototype.orElse = function(default) {
    if (this.isNothing()) {
        return Maybe.of(default);
    }

    return this;
};
