Some (internal) fixes required for light attenuation.

We need to update the example in the README.md + docs landing page.

This is now failing from a bug in Oceananigans, I'll make a PR there (CliMA/Oceananigans.jl#3383) and maybe just change how the temperature is set in this example for now (since it doesn't have any movement it can just be a function field instead).

[jagoosw]

Actually changing this example to have a function field makes it quite messy since T is a tracer required by the bgc model so we would have to predefined all of the tracers like:

clock = Clock(; time = 0.0)
T = FunctionField{Center, Center, Center}(temp, grid; clock)
P = CenterField(grid)
N = CenterField(grid)

model = NonhydrostaticModel(..., tracers = (; N, P, T))

Which takes away from our demonstration of the automatic setup. I am going to try and run the example with a temperature forcing that is the derivative of the prescribed temperature and see if the time resolution is sufficient for it to work correctly.

[jagoosw]

Should we merge #156 then this with a minorpatch version update, then #155 then minor release?

[navidcy]

We can just do a minor update when all three are merged?

[jagoosw]

Oh yeah I meant patch but we can just merge them all and do a minor release when #155 is merged
