Add ISS Duration to sensor attributes

Please add the duration to the sensor. Given the trees around my home it doesn’t make sense for the kids and I to go out and view the ISS if it’s less then a 3 minute pass as we wouldn’t see it.

The API being called in the component already returns the duration, I would like to see it added to the sensor, this would allow me to get rid of yet another app I run to notify me.
