MID 0101 Fix SpeedOrPressStatus Converter

[tecnologic-srl-roberto-guerzoni]

Hi, trying the use of MID 0101 I noticed that the data conversion for the spindles is wrong.

Fix

public override IEnumerable<SpindleOrPressStatus> Convert(string value)
{
    for (int i = 0; i < value.Length; i += 18)
    {
        var spindleValue = value.Substring(i , 18);  //  value.Substring(i * 18, 18);
        ...
    }
}
