In some cases the file might be called "temp" instead of the usual format "temp<index>_<item>"
as described in the kernel docs: https://www.kernel.org/doc/Documentation/hwmon/sysfs-interface
In this case, treat this as an _input file containing the current temperature reading.

Named return variables should only be used to describe the returned type
further, e.g. `err error` doesn't add any new information and is just
stutter.
The chip label generation has been changed in #334 to prefer the
unique device path (e.g. the location on the PCI bus) due to #333.
Here, a new annotation metric ``node_hwmon_chip_names`` is
introduced which allows to link the unique chip sysfs path to a
human-readable chip name which may not be unique among chip sysfs
paths (for example, dual-slot systems have multiple
chipType="coretemp" sensors).
This allows to mitigate the downsides of the solution to #333
(namely that the device path may not be stable across kernels and
reboots) for cases where it does not matter that multiple devices
may have the same human-readable name (e.g. aggregation or where
at most one device with a common chip name is present).
For cases where no human-readable name can be derived, the
annotation metric is not emitted.
* Prefer device path based names over exported names
For some sensors (like coretemp) it is possible that multiple
instances exist, thus base the name on the device path and not on
the exported name.
* Update end-to-end test for dual socket machines
Explicitly have 2 coretemp instances with a symlink for the device
such that the hwmon collector must pick that name (or fail)
* Add hwmon support (mainly known from lm-sensors)
This commit adds initial support for linux hardware sensors, exported
through sysfs.

* Add end-to-end test with some real life data
* Cleanup comments on hwmon collector
* Drop raw sensor name from hwmon output
* Let the sensor label be "sensor"
* Add hwmon short description to README.
