uses a shorter training window (2 years vs 20) and simplifies the code a little
[ ] need to benchmark and compare this to the previous version

Digging into this further, it appears that this parameter setting isn't as dire: even though make_start_day_ar returns 2003-12-31 as the start date for the ntrain_nowindow forecaster, the healthdata.gov hospitalization data only goes back to 2020-01-06, so the effective training set is much smaller.

Going to close this for now. We can investigate training windows another time.
