[Bug-datamash] Feature request: ignore NaN

[Brandon Invergo]

Hi Assaf,

I have a small feature request: to ignore cells that are empty or
contain NaN (or NA) when calculating stats like the mean on a column.
In other words, like R's "na.rm" parameter.

Currently, if there's an NaN in a single row, the entire mean is NaN.
If a cell is empty, datamash returns an error (invalid numeric input).
It would be nice (well, necessary in my case) to be able to tell
datamash to ignore those values.

Other than that, I'm finding datamash to be super useful.

Cheers,
Brandon
