core Removed rounding of durations in Here Travel Time sensors

Proposed change

Previously, time sensor values were rounded off, reducing their accuracy. Having untouched float values allows automation to have the arrival value to the second, and the history graph to be more precise. Finally, this doesn't cause any inconvenience, as the UI only displays one digit after the decimal point, and for automations there's the states(entity_id, rounded=True) template.
