The code now has fewer assumptions about the data which nvidia_smi can deliver. On some GPUs (probably some cheap models) it many parameters may have a value of "N/A", and those are now ignored. Also, the GPU memory is better read from the gpu_fb_memory_usage_used value, at least on the GPUs I've tested. So the number of memory related performance data has been expanded. Maybe the memory_util monitoring point should be removed, unless we know for sure that it is really useful with some GPU/driver combinations?

These changes have been running in several setups for a number of weeks, involving several different NVIDIA cards, including a very primitive one which can only report GPU temperature and GPU clock frequency.
The pull request does not contain an updated MKP; I can add an updated MKP, if needed.
