Robust Testing of OPR

[Techno11]

As stated by @cheer4ftc in #272

It would also be great to test the TOA OPR calculation on a test event like the one at the link below, where every team has played in two matches and scored 400 points except for one alliance that scored 500 points. This is an example of a case where the OPR calculation can result in very non-intuitive results and where other measures may be better.

For the record, here were the OPRs at the IL championship event after 2 matches played per team. Shows that OPRs can be crazy (and useless) until teams have played 3-ish matches (though simple averages or MMSE-calculated OPRs can be useful earlier).
