1303169663 I_kwDOCGYnMM5NrMp_ 453 'unclosed file' warning when using insert_upsert_implementation from Python 311257 closed 0     1 2022-07-13T09:34:35Z 2022-07-15T21:52:25Z 2022-07-15T21:52:21Z NONE  

I'm using the [insert_upsert_implementation](https://github.com/simonw/sqlite-utils/blob/main/sqlite_utils/cli.py) function directly in my Python code to import a csv file with all the bells and whistles sqlite-utils provides, but I'm getting a resource warning that a io.TextWrapper object is not closed.

The warning goes away when wrapping the code from this line in a try/finally block like:

try: ... ... finally: decoded.close() (might be that sniff_buffer must also be closed if non null, but I might be wrong)

I suspect Python closes the reference automatically when the sqlite-utils cli run is done, but since my code doesn't exit, I'm getting the warning.

Alternatively, it'd be cool if the 'import csv/tsv' functionality could be added directly to the Database class.
