Remove default lines

We can remove these lines as carbonIntensity is set in the function args carbonIntensity = GLOBAL_INTENSITY

Updated:

  perByte(bytes, carbonIntensity = GLOBAL_INTENSITY) {
    const energyBycomponent = this.energyPerByteByComponent(bytes);

    // otherwise when faced with non numeric values throw an error
    if (typeof carbonIntensity !== "number") {
      throw new Error(
        `perByte expects a numeric value or boolean for the carbon intensity value. Received: ${carbonIntensity}`
      );
    }

    const co2ValuesbyComponent = this.co2byComponent(
      energyBycomponent,
      carbonIntensity
    );

    // pull out our values…
    const co2Values = Object.values(co2ValuesbyComponent);

    // so we can return their sum
    return co2Values.reduce(
      (prevValue, currentValue) => prevValue + currentValue
    );
  }

This issue seems to be resolved/is dated. @drydenwilliams I'm going to mark it as closed.
