ethereum base fee, one row a day

for every day: the block range, the min, p25, median, p75, p90 and max base fee in gwei, the cheapest and the priciest hour, how full the blocks were and the median blob fee. the workflow writes them to daily.csv in the gasweek repository, and a copy sits on this site as gasweek-daily.csv.

the commit column comes from git blame on my machine. each commit it names is on the commit list of gasweek with its signed record; the history that ties a row to its commit stays off this site, so you cannot rerun the blame from here.
