simple duration printout

[RiesBen]

This pr brings simple duration timings to the cmd line tools:

• plan_rbfe_network
• plan_rhfe_network
• quickrun

adds this line to the output: Duration: 0:00:30.134822
it is a super small code change, that adds a decorator to the cli tools.

so currently write will print to stdout, but this will make stdout noisy if you're also using that for the actual output of the command

I don't think you need something as complicated as how openmmtools does it: https://github.com/choderalab/openmmtools/blob/main/openmmtools/utils/utils.py#L65-L183

But I much rather see the timing information written to a log level (maybe info?) so that a user can control where the output goes using either standard python logging tooling or posix things like 2&> /dev/null

I opened OpenFreeEnergy/gufe#168 which I think is a better system that @mikemhenry is alluding to. This is good enough and a nice improvement for 0.7 though
