Where’s the H1Bs? Didn’t see them in the legend, but might have missed em since that legend is legendary

H-1B is a nonimmigrant visa. I downloaded both and they'll automatically update to that repo as JSONL, but I only made the CSV and EDA for immigrant visas.

But a PR is welcome. The steps should be mostly the same for the non-immigrant data. Check the fixup files and then the R code in the Readme. The CSV report at the bottom was made with `lb eda --end-row inf $file`
