Add (option for) total brew timer including draw down time about cofi

I was thinking about it, and I think the best way to approach this is to have a new step type "stopwatch" that you could set at the end of the brew and it would automatically start counting up without upper bound.
WDYT would that solve your usecase? @elumbella

I'm not sure, but I can be convinced :D Of course, the timer would have to include all the time from the steps before.

I personally would have liked maybe a switch when creating a recipe and a total time counter that runs somewhere during the process. But I'm open to try your suggestion! Maybe other people could also voice their preference before you commit to implementing?
