dbus-sensors: utils: Utility to get device bus & addr from dev name.
This is applicable to all the services which rely on "bus-addr" fmt.
1. FanSensor
2. HwmonTempSensor
3. IntelCPUSensor
4. PSUSensor
In addition this would also fix Fansensor Daemon crashes due to
stoi() exceptions weren't caught earlier.
For example: In a FanSensor Daemon -
Device of f0103000.pwm-fan-controller would be classified as i2cfan
based on new way of defining fan type.
Hence when we parse string for bus-addr, bus=f0103000.pwm and
addr=fan-controller for which stoi() would crash.
This would be true for all non I2c devices defaulting to I2cFan type.
Solution is to use 'std::from_chars' which handles under/overflow
properly. Centralizing this now in Utils would also allow us to manage
this appropriatelty across various services.
Tested:
Tested sanity of all daemons in the system and they work as expected.
