Hot fix to increase the robustness of the code

This release features the following changes:

• a hot fix to prevent the warm start (i.e. restarting from a previous state) to occasionally fail due to small approximation errors (order of magnitude: 10exp-12) when writing and reading the state files;
• updates to the reporting options for output maps. List of repStateMaps files is now the same as repEndMaps and it only contains files used to warm start the model. Additional reporting options are available to singularly output maps of different model variables.
