ci-group/revolve2: 1.2.3

Changes Added possibility of visualization of the genotype to phenotype body mapping Added a new example to learn how to fetch morphological traits of individuals Added calculation of population diversity using Euclidean distance of morphological traits Added calculation of population diversity using the edit-tree distance of morphological traits Removed hidden units from the multineat generating the initial genotypes that seemed to be causing bias towards already picked modules (temporal fix, will need more study) Added camera support for v2 physical interfaces Fixes Fixed an error occurring from manually closing the simulation while the framework still tried to render the scene Corrected some incorrect measures for v2 body Fixed the incorrect CPPN output that was being used
