staccato: init at 0.1.6

Add the package `staccato`, "a command line program that lets you
compute statistics from values from a file or standard input".

I have tested this change per nixpkgs manual section 13.1 ("Making
patches").

+      Staccato (`st` for short) is a command line program that lets you
+      compute statistics from values from a file or standard input. It
+      computes things about the stream of numbers like min, max, mean, median,
+      and standard deviation. It can also compute these things about some
+      subset of the stream, for example the lower 95% of values.
