parseOptions validates args it is not supposed to get for perByte(Trace) functions

[alexzurbonsen]

Describe the bug
When you call perByte or perByteTrace the function parseOptions also validates args that it cannot get (dataReloadRatio) It logs a lot of stuff which can be consufing in the logs since you get messages that do not apply. Also I am not sure it needs logging at all. After all the values are optional in to begin with. <-- this does not happen for perByteTrace options.

To Reproduce
Steps to reproduce the behavior:
Call perByte and observe console.logs.

Expected behavior
No misleading logs or in this case even better: no logs at all.

Hi Alex. Can you please give a code example using both perByte & perByteTrace which returns the logs?

[alexzurbonsen]

Hi fershad, of course, at least for perByteTrace. I am not sure anymore, why I also mentioned perByte - I guess that is wrong - as far as I can see the parseOptions call is responsible for the logging.

swd.perByteTrace(
      1000,
      undefined,
      co2jsOptions,
    )

where co2jsOptions is of

type CO2jsOptions = {
  greenHostingFactor: number;
  gridIntensities: {
    device: number | null;
    dataCenter: number | null;
    network: number | null;
  };
};

I simplified CO2jsOptions a little here.

Cheers Alex. Yep, I can see that now for perByteTrace.

import { co2 } from '@tgwf/co2'
const estimate = new co2({ model: "swd", version: 4 })
const bytesSent = 1000 * 1000 * 1000; // 1GB expressed in bytes

const options = {
    greenHostingFactor: 0,
    gridIntensities: {
      device: 450,
      dataCenter: 209,
    }
  };

const estimatedCO2 = estimate.perByteTrace(bytesSent, undefined, options);
console.log(estimatedCO2);

Running the code below sees the following console output:

The dataReloadRatio option must be a number. You passed in a undefined.
Falling back to default value.
The firstVisitPercentage option must be a number. You passed in a undefined.
Falling back to default value.
The returnVisitPercentage option must be a number. You passed in a undefined.
Falling back to default value.

{
  co2: 148.2,
  green: false,
  variables: {
    description: 'Below are the variables used to calculate this CO2 estimate.',
    bytes: 1000000000,
    gridIntensity: {
      description: 'The grid intensity (grams per kilowatt-hour) used to calculate this CO2 estimate.',
      device: [Object],
      dataCenter: [Object],
      network: [Object]
    },
    greenHostingFactor: 0
  }
}

Those first three lines are the superfluous warning messages that are being returned, despite being not relevant to the perByteTrace function.

Yes, that's it. Thank you for looking into it :)

@alexzurbonsen I won't be able to take a proper look at this until early October. If you've got time and capacity between now & then, we'd welcome a PR which I could review when I'm back from leave.
