fanctl: Add option to display sensors

Add a new 'sensors' option to fanctl to display sensor values for debug,
which the code gets straight from D-Bus.

The help:
$ fanctl sensors -h
```
Retrieve sensor values
Usage: fanctl sensors [OPTIONS]

Options:
  -h,--help                   Retrieve sensor values
  -t,--type TEXT              Only show sensors of this type (i.e. 'temperature'). Optional
  -n,--name TEXT              Only show sensors with this string in the name. Optional
  -v,--verbose                Verbose: Use sensor object path for the name
```

Example output:

$ fanctl sensors
Altitude:                          110.901
Ambient_0_Temp:                    22.562
Ambient_1_Temp:                    22.604
Ambient_2_Temp:                    22.4047
Ambient_Virtual_Temp:              22.562
Battery_Voltage:                   3.144
NVMe_1_Temp:                       31
NVMe_2_Temp:                       31
NVMe_JBOF_Card_C10_Local_Temp:     33.938
NVMe_JBOF_Card_C10_Temp:           44
...

Display the object path for the sensor name:
```
$ fanctl sensors -v

/xyz/openbmc_project/sensors/current/vcs_p1_dcm0_rail_iout:                 2.75
...
```

Display only voltage sensors:
```
$ fanctl sensors -t voltage
Battery_Voltage:              3.144
ps0_input_voltage:            207
ps0_input_voltage_rating:     220
ps0_output_voltage:           12.296
...
```

Display only sensors that contain the substring 'core':
$ fanctl sensors -n core
```
proc0_core0_0_temp:   44
proc0_core0_1_temp:   44
proc0_core10_0_temp:  45
proc0_core10_1_temp:  45
...
```
