feat(jumpavg): speed up, use Python 3.8 features

+ The main speedup comes from abandoning copy.deepcopy(),
  doing shallow list copies (at most) and introcuding copy_fast().
+ Turn into dataclasses whenever possible, use type hints.
+ Simplify the partition search code,
 + It is now clearer the time complexity is O(N*(N+n)),
   where N is number of samples, and n is the average size
   of the last group of the current record glist.
+ Used black for formatting, so no u"" anymore.
+ Update metadata for 0.3.0 release.

+0.3.0: Considerable speedup by avoiding unneeded copy. Dataclasses used.
+       Mostly API compatible, but repr looks different.
+
+0.2.0: API incompatible changes. Targeted to Python 3 now.
+
 0.1.3: Changed stdev computation to avoid negative variance due to rounding errors.
 
 0.1.2: First version published in PyPI.
