Misleading progress bar against utf-16-le CSV input

The program crashes without any error.

wget "https://artsdatabanken.no/Fab2018/api/export/csv"
sqlite-utils create-database test.db
sqlite-utils insert --csv --delimiter ";" --encoding "utf-16-le" test test.db csv

I would like to highlight various issues:

1. sqlite-utils catches exceptions without printing the stacktrace and/or reraising the exception, so there is no easy way to use pdb or similar to debug the program, solution: add a debug option
2. Silent crash: this is related to (1.), and it happens when there is a catch-all mechanism; solution: let the program fail.
