Update workflow for timeseries and summary generation to regard user preferences within configuration file

Current workflow currently takes all available data for timeseries and summary processing, regardless of if configuration file is marked to process for a given time period. Include checks when generating timeseries to heed to the "processing" entry in the configuration file.

Start by locating the workflow that generates timeseries and summary data, then inspect how it reads the configuration file and its "processing" entry. Confirm the current behavior with available tests or a small configuration example; done means periods not marked for processing are excluded from both generation paths.
