Refactor jumpavg to be more readable and usable

This is the python3 change, the python2 is still used for testing bisect.

+ New version is 0.2.0 due to amount o API changes.
+ Jumpavg is now part of CSIT resource package tree.
+ Perpatch migrated to new jumpavg.
- PAL NOT updated (the update moved to a different Change).

-"""Script for determining whether per-patch perf test votes -1.
-
-This script assumes there exist two text files with processed BMRR results,
-located at hardcoded relative paths (subdirs thereof), having several lines
-of json-parseable lists of float values, corresponding to testcase results.
-This script then uses jumpavg library to determine whether there was
-a regression, progression or no change for each testcase.
-If number of tests does not match, or there was a regression,
-this script votes -1 (by exiting with code 1), otherwise it votes +1 (exit 0).
