Update crosswalk using year 2020 data

[grgmiller]

It appears that the R script is using year 2018 EIA-860 data to construct the crosswalk. I suggest in the next release updating this to use year 2020 data (or the most recent year of data available) to run this. This may potentially fix some issues with missing associations.

The EIA data year is one of the parameters that can be set in the code (see line 92). In the next release we will update the default starting value.

`## Assign key values for data retrieval api_key <- "YOUR_API_KEY" eia_860_year <- 2018 # The EIA data year (available at https://www.eia.gov/electricity/data/eia860/) earliest_retirement_year <- 2010 # All units retired before this year are filtered out of the data

Thanks - for those of us who are not familiar with R or do not have R studio installed, it makes it challenging us for us to update this on our own.

Do you happen to have any update on when the next version of this crosswalk will be released?

@jeremyschreifels Would it be possible to add a feature that allows users to input more than one year of EIA data? Alternatively, it could be interesting to have a temporal version of the crosswalk that uses year as a primary key.
