to_h3j

Write H3 hexagon data out as an h3j-compliant JSON file
NOTE: the column containing H3 hashes must be named <code>hexid</code>

Provides friendly wrappers for creating 'duckdb'-backed connections
to tabular datasets ('csv', parquet, etc) on local or remote file systems.
This mimics the behaviour of "open_dataset" in the 'arrow' package,
but in addition to 'S3' file system also generalizes to any list of 'http' URLs.
