sensors -j give JSON output, which is much easier to parse than
raw output.
Use this, together with the "path" parameter, to allow robust reading of
sensor values.
fixes#308
On intel pstate drivers only the normal frequency is written to /proc/cpuinfo, not accounting for scaling/turbo.
This should fix that, though it needs testing on other computers (AMD, intel without pstate) because I am not
certain that the file only exists on Intel pstate.
was having some problems with the current implementation as i have multiple values with the same name in sensors -u.
this way it is unambiguous and *should* just work everywhere with no lm_sensors required, though some distros might move the pseudo file elsewhere, not sure, but thats why it is configurable.
testing would be great.
also, the file is simpler too.
