Latest versions are not CommonJS compatible

[lancedikson]

Hi again 😄 My applications are failing now as the latest released versions of @sweet-monads are not CommonJS-compatible for some reason. You might have changed something in the compilation settings? The 2.0.0 version is compatible and the later ones are already not:

// 2.0.0 exports
exports["default"] = MaybeConstructor;
exports.merge = MaybeConstructor.merge, exports.just = MaybeConstructor.just, exports.none = MaybeConstructor.none, exports.from = MaybeConstructor.from;
exports.isMaybe = function (value) {
    return value instanceof MaybeConstructor;
};

// 2.1.2 export
export default class MaybeConstructor {
    constructor(type, value) {

So, Node 12 (which is LTS still) fails to run such apps. Should we consider it as a bug or it's something that meant to happen? :)

Oh, will fix it soon. Thank you a lot.
