Workout HeartRate Datafield (Wahoo Like)

This heart rate data field is an evolution of my "Wahoo-like coloured HR Datafield" which dynamically changes its color based on the cycling heart rate zones. It retrieves the cycling heart rate zones via a system call from your user profile in Garmin Connect. Additionally, this data field changes its color based on the target heart rate zones defined within the training file when performing a training. So, when you are within the target range, the background color will be green. In case you are above the range, it will be red. When within 2% below the minimum target, it will show the value in blue, and when below this, it will be red. Also in case you are wihtin 2% above maximum target, it will show the vlaue in orange and above that, it will be red. In addition, it will also show arrows beside the value which are either pointing down or up, depending on whether you are below or above the target range.
