fail to encode array of nested classes

[FloorLamp]

I have 2 classes with custom encoding:

class Serializable {
  serialize () {
    const encoder = new cbor.Encoder()
    this.encodeCBOR(encoder)
    return encoder.finalize()
  }

  static deserialize (serialized) {
    return cbor.decodeAll(serialized)
  }
}

class TestA extends Serializable {
  encodeCBOR (gen) {
    return gen.write(44)
  }
}

class TestB extends Serializable {
  encodeCBOR (gen) {
    return gen.write([
      new TestA()
    ])
  }
}

This works fine and TestB serializes to <Buffer 81 18 2c>. If I update TestB to this:

class TestB extends Serializable {
  encodeCBOR (gen) {
    return gen.write([
      new TestA(),
      true,
    ])
  }
}

Then it serializes to <Buffer 82 18 2c>, which has the correct length but not the new element. Attempting to decode that throws a Error: Undeterminated nesting.

@dignifiedquire mind taking a look?

Thanks for the report, fixed in #28
