Colour sensor should return 0-255 instead of 0 -100 in general

[VinArt]

Describe the bug

• If one would print out the RGB values gotten from colour sensor on the EV3 screen in simulation the overall range is form 0 to 100 and not from 0 to 255

To Reproduce

• Create such a program:
  
• Run in simulation with robot view open

Expected behavior

• Values would be from 0 to 255

Device information

• OS: Linux
• Browser Chrome 75

Additional context
Actual EV3 HAL implmentation has the following:

public synchronized ArrayList<Float> getColorSensorRgb(SensorPort sensorPort) {
        SampleProvider sampleProvider = this.deviceHandler.getProvider(sensorPort, ColorSensorMode.RGB.getValues()[0]);
        float[] sample = new float[sampleProvider.sampleSize()];
        sampleProvider.fetchSample(sample, 0);
        ArrayList<Float> result = new ArrayList<>();
        result.add((float) Math.round(sample[0] * 255.0f));
        result.add((float) Math.round(sample[1] * 255.0f));
        result.add((float) Math.round(sample[2] * 255.0f));
        return result;
    }

and since samples are from 0 to 1, then the overall result should be from 0 to 255

BTW, it treats transparent as black.

not solved in #215

Please also check this in all robots systems, simulation and real robots!

The simulation part was solved by a GCI student in PR #379.

If the issue is still open, I would like to work on this one.

[boonto]

Do you have a real EV3 to test with? The simulation parts are already solved.

[schrodingersca8]

No, I don't have one.

[boonto]

Then you can't work on this sadly. Maybe check out another issue. I'll go through them soon and add some "good first issue" labels, so stay tuned for that.
