High vertical resolution with 0.25° horizontal resolution

[wghuneke]

Run an experiment using OM2-025 but with the high-resolution vertical grid of OM2-01. This experiment is low priority but could be a nice addition to complete the set of vertical resolution tests and to show that a high horizontal resolution is (most likely) also needed.

On this, it might be worth reviewing Mensah et al. 2021 to see what they say about horizontal resolution requirements for overflows.
