Add support for new climo_cdf.direct_prob flag

[JohnHalleyGotway]

Describe the Enhancement

MET PR dtcenter/MET#2034 for issue dtcenter/MET#2003 adds a new option to the climo_cdf dictionary. This task is to make this option configurable via METplus.

Also support climo_cdf in the Series-Analysis config file. It appears in the following MET config files (Series-Analysis is the only new one):

EnsembleStatConfig_default:climo_cdf = {
GridStatConfig_default:climo_cdf = {
PointStatConfig_default:climo_cdf = {
SeriesAnalysisConfig_default:climo_cdf = {

Please see feature_2003_briercl documentation for details or develop, after the PR has been merged.

Also assigning to @j-opatz since he's applying this new functionality to NOAA/CPC data and is best suited to advise on the utility of this option.
