Setting MEKE_GEOMETRIC_ALPHA = 0.06 significantly improves the Southern Ocean
MLD biases while keeping a good ACC transport. We will use this value in alpha07g,
but it will be revisited during the tuning phase.
The new default for EQN_OF_STATE is "WRIGHT_FULL" and that's what we want in
alpha07g. We will explicitly set this in MOM_interface to 1) document this
change, and 2) keep control of which EQN_OF_STATE is being used, in case the
default changes again in the future.

I did a clean timing comparison between EQN_OF_STATE = "WRIGHT" (simplified version)
and EQN_OF_STATE = "WRIGHT_FULL". The differences are within machine uncertainty,
so we will proceed with using WRIGHT_FULL in the next tag.

EQN_OF_STATE = "WRIGHT_FULL"
Model Throughput:        13.84   simulated_years/day

EQN_OF_STATE = "WRIGHT"
Model Throughput:        13.63   simulated_years/day
