Changelog:

• Enhancements
  • net_if_stats()'s isup also checks whether the NIC is running (meaning Wi-Fi or ethernet cable is connected).
  • improved battery detection and charge "secsleft" calculation

• Bug fixes
  • physical cpu_count() result is incorrect on systems with more than one CPU socket.
  • sensors_battery(): if percent can be determined but not the remaining values, still return a result instead of None.
