Quarter averages

[tiffanychu90]

segment speeds

• sketch out quarterly and year segment speed averages following Speed averages (year and year-quarter grains) #1267
• add a quarter_year_averages.py script to see how we can aggregate segment speeds over all the dates we have
• bring in segment geometry with speed averages and then average over a quarter or a year (~25 min for year grain, which feels too high)
• TODO:
  • there is a bottleneck when bringing in segment geometry -- bringing it in every day before being able to average it seems expensive
  • essentially we want to be able to look across a lot of dates for segment geometry and dedupe ahead of time, then bring it in after we average speeds (tabular)
  • time_series_utils concatenation function that uses dask.delayed is running into limits...look into other options for how to read in many dates of data at once
