Is your feature request related to a problem? Please describe.

In some cases, not all rows of a CSV file might be useful to import into a database. By using filters, it might be possible to delimiter a subset of data to import.

Describe the solution you'd like

Filters could be logical expressions with END, OR, and NOR, comparing columns and values. Filters are strings passed as argument, to be interpreted as logical expressions. The expressions are used while reading a row to include or exclude it.

Describe alternatives you've considered

When using a staging table, the application can do the filtering there before updating its core tables. But when inserting into a core table directly, we may have issues with unwanted data.
