#2310 new defect zcol should not be compulsory when method=n

In, zcol is not necessary when method=n since all does is count the points. However, by default the module defines z=3, which means that max_col becomes 3 and thus, for a simple file with only x and y coordinates, max_col > ntokens (line 679 of main.c) and the modules fails with

ERROR: Not enough data columns.

As it seems impossible to unset z, the only solution is to add a third, bogus, column to the input data.

The code seems pretty much designed with the idea that a zcol is present and it does not seem super-trivial enough for me do just change that.

I consider this a bug as it does seem counter-intuitive to require a zcol when a method such as n is available.
