Could gpustat show this information too?

The nvml API supports this: nvmlDeviceGetFanSpeed(). It would be straightforward to implement this. I'll give a try when I have an extra cycle, but contributions are always welcomed.

FYI: There is a similar PR #42, which lacked the CLI flag and a unit test so I was unable to merge it.

will be on v0.6:

gpustat -F
gpustat --show-fan
