SleepTK Wake features port

[cyberneel]

@thiswillbeyourgithub I came across this from a bounty page and saw that you were more interested in the wake features than the tracking. I have a branch on my personal repo where I have been working on wake features more recently and got gradual wake along with snoozing to work on InfiniTime and am looking at implementing natural wake soon. I also have the framework for sleep tracking in place, just need to create the analysis part of the data. is this something you are interested in or is the bounty already taken?
