Description
related to issue #322
acovf has an explicit check that ndim is 1, and raises a ValueError if not, to handle pandas objects/series
see
https://github.com/statsmodels/statsmodels/commit/bcdb0250696d7079190f7c45eedc5bede6312f9c
my impression is that this should work vectorized for 2d along one axis
I don't remember which versions/shapes I checked a long time ago.

Research direction
Start by inspecting the acovf dimensionality check and the behavior referenced in issue #322 and commit bcdb0250696d7079190f7c45eedc5bede6312f9. Determine the supported 2D shapes and axis semantics for vectorized acf/acovf, then add coverage showing the intended behavior and confirming pandas inputs remain handled correctly.
