nvl over time?

[spdavern]

I share some multi-GPU machines with a group of people. Sometimes running nvl (or nvgpu.available_gpus()) one time misses that someone else is interactively working on one of the GPU's but my check missed their sporatic usage. It'd be nice to have the option to get an nvl result that somehow averages the information over a user definable period of time.
Alternately, if the nvl output was compatible with the watch command I could do watch -n 3 nvl. Instead I get characters watch can't display nicely.

Anyway, great tool! Thank you!
