Compact AFL schedule results in incorrect round numbers for 2020

[cfranklin11]

Since get_fixture() uses week-of-year to calculate round numbers, the new, compressed AFL schedule messes with that, because the only thing better than one round of footy per week is two rounds of footy per week.

Below is a copy/paste of the last 10 rows. According to footywire, round 12 should start on 2020-08-13, but it's still "week 11".

I've implemented fixes for similarly-irregular rounds before, so I'll work on a fix, and should have a PR soon.

I was thinking this would be the case. Thanks @cfranklin11
