Right now the EIA 861 and FERC 714 interim ETLs process data for all years for both the full and the fast ETL. As we add more of this data into dagster, and notably as we incorporate the service territory analyses (#2437), the inability to subset this data by year is causing memory issues for the CI.

To make this change, we would need to do the following:

• For FERC 714 data: Change the extractor to read in the CSV files (which are not time-subsetted) and subset data by years (closed by Filter FERC714 ETL by year #2649)
• For EIA 861 data: Currently, discontinued tables break the single year ETL. To enable subsetting by year, we'll need to address this issue first. See Address issue where 861 ETL fails w/o all years of data #1671, Convert EIA-861 ETL to use Dagster #2265. We should decide at what stage we want to do the subsetting.
