RRFS A Ensemble changes (#222)

* These are the changes that were necessary to get the RRFS A Ensemble graphics running.  Previously, the figure_builders.py would check would check for members even if they weren't present, and even if ens_size was set to a number lower than the default (10).  Now it will skip looking for members higher than theens_size.  In create_graphics.py, The fhr is needed in the call to create_maps as a list, or parallel_maps will crash.  The fields for most unstable CAPE and most unstable layer CAPE are not available, and are removed from the rrfs_ens.yml file.

* Added test in figure_builders.py to set the last_panel in order to add the colorbar.
