QPR-12883 -- Add SIMM calibration files to open source and fix OREApp so that it can run new versions, i.e. versions that are not listed in the SimmVersion enum

 The SIMM Calibration can be used to add or override SIMM versions by specifying the risk weights, correlations,
 concentration thresholds along with associated buckets/labels and currency groups (for risk class FX and IR).
+
 See Example\_44 for a full SIMM calibration file for SIMM 2.5A \cite{SIMM2.5A}.
+The official configuration files for each version (SIMM 2.2 and greater) can be found in folder {\tt Configurations/SIMM/}
 
 The file consists of a {\tt <SIMMCalibrationData>} node, with {\tt <SIMMCalibration>} subnodes that each define a given
 SIMM version, as in Listing \ref{lst:simmcalibration_data} below.
