update to https://dynamical.org/scorecard

- added ECMWF IFS ENS and NOAA HRRR
- utilizes our asos-parquet for observations
- calculates lots of different metrics for temperature/precip. statistics are read on-demand from a statistics.parquet

it's still just for fun and possibly wrong (lol). figuring out the "right" metric for precipitation is hard! especially when forecast product spatial resolutions differ (don't want to reward smooth "safe" forecasts)
