Multicol CLUBB (#1193)

* Adding column loop to run_clubb

* Lot more changes

* Adding multicolumn output support and improving stats code.

* Conditionally closing stats files. This is just a bug fix. I'm not sure how this ever worked without the conditionals.

* Improvements and some cleanup.

* Bug fix

* Merge with master

* Removing num_standalone_columns, it's no longer needed.

* Changes to make CPU vs GPU test work with new multicol mode. Columns now run with different parameter sets, tolerance script checks average diff instead, increasing number of cobra timestep run, removing mpace_b because it turns out that cobra has ice and is capable of detecting the same ice code errors that mpace_b was added to test.

* Removing C1 from list of variables to change, it was breaking the CPU vs GPU test, and also clubb warns that 'l_damp_wp2_using_em = T requires C1=C14 and l_stability_correct_tau_zm = F', so perhaps chaning it is just unstable. I've confirmed that GPU bugs are still dectable though.
