No sensor updates because of throttle

[GHswitt]

When using throttle it will not publish every frame to the sensors. This is ok when a frame contains all sensors/values which is the assumption of the current throttle algorithm. However after extensive debugging I've found that my SmartShunt 300A does not include all values in every frame:

There are two different frames. One including H1-H18 and one for data I am interested in (V/I/P).
For me it happend that it only published the Hx frame, depening on the timing, but it never updated the other one.

I think the throttle algorithm requires a rework.

I've created and tested a fix: GHswitt@89eb8db

It will throttle per frame by computing a hash of all the labels a frame includes. With this it is possible to differentiate the different frames and keep a 'last published' time for each frame type.
