The csv module documentation says this is necessary in some cases, such as for parsing embedded newlines in quoted fields. Refer to the <https://docs.python.org/3/library/csv.html#id3>.
For seekable streams, the delimiter is sniffed from the first 1MB of data. This should provide enough rows to the sniffer even for datasets with very long rows without blowing up memory usage much. A csv.Dialect may also be specified directly to load_csv() for programmatic usage.
Useful when you want to disable sniffing or when one or both of the files aren't seekable, so sniffing doesn't work.

Nice tool, I just want to use it on TSV too. See commit messages for details. :-)
