A Delete at time T marks a Put at time T as deleted.
In parent I invented special logic that insert a virtual millisecond into the tr if the encountered KV is a delete marker.
This was so that there is a way to specify a timerange that would allow to see the put but not the delete:
Discussed this today with a coworker and he convinced me that this is very confusing and also not needed.
When we have a Delete and Put at the same time T, there is not timerange that can include the Put but not the Delete.
So I will change the code to this (and fix the tests):
It's easier to understand, and does not lead to strange scenarios when the TS is used as a controlled counter.
Needs to be done before 0.94 goes out.
