* -F or --allow-existing: Proceed (without deleting existing data) if the metadata or tiles table already exists
or if metadata fields can't be set
* -t _directory_ or --temporary-directory=_directory_: Put the temporary files in _directory_.
If you don't specify, it will use `/tmp`.
* -P or --read-parallel: Use multiple threads to read different parts of each input file at once.
This will only work if the input is line-delimited JSON with each Feature on its
own line, because it knows nothing of the top-level structure around the Features. Spurious "EOF" error
