update overhead/efficiency

[casperdcl]

Things like nvidia-smi can take some time to run (up to a few seconds) so we should try to call them only once per update. Right now, using e.g. #{gpu_icon} #{gpu_percentage} will call nvidia-smi twice.

Fixing this will also help with #5

also @ctjhoa considering #22 #27 #28 #29 and git fame -wtMC --excl='\.png$' I'm responsible for about 1/4 of this repo (LoC) or 1/3 (files) - would be nice to be added as a collaborator/team member :)

Sure, that's what I had in mind. Unfortunately, I don't think I'm able to do that myself. As this plugin is part of the tmux-plugins organization, only the organization's owner is able to add new collaborators.

@bruno- can you add @casperdcl as collaborator of this project, please? Thanks

Since github upgrade I've managed to invite you as collaborator. Another information not directly related but with 0e6fb34 I have added customization on the format used to display percentage. So I've change the default gpu_percentage_format to %3.1f%% (formerly %3.0%%) which add one decimal, this was needed to get the same behavior between cpu and gpu. Thanks
