A fast version of a somewhat subset of <csvkit>, written in <C (programming language)>.

Build failed with `undefined reference to pcre_config` on <Ubuntu 23.04>: https://github.com/DavyLandman/csvtools/issues/18

Unfortunately it is lacking some basic options, like optional header + selecting column by index on `csvgrep` (though `csvcut` has it). The project seems kind of dead.

Also unclear if it allows to filter + print only selected columns.
