  ENH: Avoid memory peak and useless computations when printing a MaskedArray.

Ref #3544.

When printing a `MaskedArray`, the whole array is converted to the object dtype,
whereas only a few values are printed to screen. So the approach here is to cut
the array and keep only a subset that it used for the string conversion. This
way the output should not change.
