Calling methods on proxied Buffer crashes with error "TypeError: argument must be a buffer"

[MZanggl]

If you use an object that contains a buffer (for example _id coming from MongoDB), calling methods like toString crash with the error "TypeError: argument must be a buffer".

Here is a test that verifies this:

it("Proxied Buffer.toString outputs the pristine Buffer.toString", async (assert) => {
    const model = { id: Buffer.from("5fea9621e6efdf282752f5ba") };
    const proxy = ObservableSlim.create(model);

    expect(proxy.id.toString()).to.equal(model.id.toString())
});

@MZanggl My apologies for not seeing this until now! I'll take a look into this to see what can be done. However, Observable-Slim in general is intended to be used with "plain" objects. Specialized objects like Date even have trouble with native Proxy functionality let alone Observable-Slim.
