Location of iuvolt script

[berglh]

I just thought I'd chime in on the best practices location for this type of utility. My understanding is that a script that requires running as root should live in /sbin/ or /usr/sbin. Scripts or binaries to run in user space without super privilges belong in /bin or /usr/bin

I'm not really fussed eitherway, I just thought I'd point it out. If I get around to experimenting with this solution on my XPS 9570 I may make a pull request, jost poking around for now.
