suzerain: rename 'rms' -> 'meanrms'

Better naming for a #3058 fix that's forthcoming.

suzerain: #3058 supply mean in "mean"

I had been supplying the mean absolute conserved state due
to using compute_field_L2xz's "mean" result.  On a laminar
profile, these things can coincide which may explain why
they have not been problematic in the past.  Update the
code to provide the pointwise mean conserved state to Largo.
