Environment upgrade: Cloud condensation level

[bayliffe]

Recent changes to the cloud condensation level code and acceptance test data were started and completed whilst the environment upgrade was underway. As a result they were not capture in the upgrade process.

The KGO are variously modified, e.g.

The changes are generally small, but larger than precision. The plots below show the changes:

Temperature

Pressure

The newton iterator within the plugin is returning answers that differ at a couple of decimal places. This can also in turn result in the masking within the plugin being different as the value comparison shakes out slightly differently.

mask = ccl_pressure > self.pressure.data

Old environment mask 1 point:
ccl_pressure [89759.96]
pressure [89677.25]

New environment masks 7 points:
ccl_pressure [102487.88 102200.26  89759.96 102076.51 102490.13 102371.01 101566.38]
pressure [102487.875 102200.25   89677.25  102076.5   102490.125 102371. 101566.375]

Changes look okay to me.
