PLRsearch: Use stat trackers to shorten Integrator

+ Extract several tracker classes and use them in Integrator.
+ Apply next_rate workarounds to focus more on critical region.
+ Rewrite stretch function, as the previous implementation was wrong.
+ Rework logging:
++ Use injected trace() function in Integrator.
++ Inject function that skips trace logging on default initialization.
++ Use the same multiprocessing-safe passing, but separate queue.
+ Set duration to 120m in Robot, but keep at 30m in Python.
+ Apply minor changes to make computations more reproducible:
++ Attempt to log everything needed by reproducibility in one line.
++ Log samples used, and make it settable as upper limit.
++ Use repr output in TRex scripts, to avoid rounding when copypasting.
+- Numpy seems to be sharing PRNG between processes.
+-- An edit to disable one thread is needed for full reproducibility.
+-- Such an edit is prepared, but will not be merged anytime soon.
