Allow dim in get_bitinformation as list

This would be most welcome, as I just hit this issue with our ROMS model, which uses a C-grid, and therefore variables on different cell locations have different dimensions.

I'd like to specify the "y" dimensions in a list, e.g. dim = ['eta_rho', 'eta_u', 'eta_v'] and then use whichever one is found for a specific variable.

Is that what you had in mind?

For now I would transpose and/or use axis=1
