We have mostly kept the same API as unihan-etl, except defaulting to JSON given the JavaScript environment. And destination also takes into account the current working directory.

• format ("json"|"csv"|"yml")
• destination (string) - Supply a path relative to the current working directory
• fields (Array|string) - e.g., kTotalStrokes; see https://unihan-etl.git-pull.com/en/latest/cli.html for choices.
• inputFiles (Array|string) - All Unihan files used by default.
• source (string) - Defaults to http://www.unicode.org/Public/UNIDATA/Unihan.zip
• zipPath (string) - Defaults to /home/docs/.cache/unihan_etl/downloads/Unihan.zip
• logLevel ("DEBUG"|"INFO"|"WARNING"|"ERROR"|"CRITICAL")
• noExpand (boolean) - Whether to expand values to lists in multi-value UNIHAN fields (excepting CSV)
• noPrune (boolean) - Whether to prune fields with empty keys (excepting CSV).
• version (boolean) - Just prints version and exits
