MARBL version with explicit calcifiers

[kristenkrumhardt]

Version of MARBL with an explicit calcifier phytoplankton functional type, based on coccolithophores; the parameterization is described in Krumhardt et al. (JAMES) .

Carbon fixation (photosynthesis) of the coccolithophore PFT sensitive to aqueous CO2. CO2 is handled as an additional nutrient required for photosynthesis.

Calcification by the coccolithophore PFT is sensitive to temperature, aqueous CO4, and PO4 limitation.

Testing update:

Ahead of helping @kristenkrumhardt make some changes following the code review earlier this month, I ran aux_pop_MARBL on hobart. Mostly positive results, and we already have plans to address the bad results:

1. This branch runs in debug mode (and with the nag compiler) -- previous tests were intel-only and without debug

2. Namelist comparisons fail due to adding variables to user_nl_marbl, but this was expected

3. The addition of two new history fields is causing minor testing hiccups, but addressing modify_Tfunc branch: better trigger than ((autotroph_calcifier)) for carbon limitation diagnostics kristenkrumhardt/MARBL#2 will fix both of these failures:

   1. cprnc now triggers a failure when a variable is in one file but not the other (this will go away because we will not be adding C_lim_surf and C_lim_Cweight_avg_100m for sp)

      Variable on file1: sp_C_lim_surf not found on file2
      Variable on file1: sp_C_lim_Cweight_avg_100m not found on file2
      

   2. exact restart tests are failing because these two fields are changing, but again this will go away because these two fields shouldn't be computed in the first place
