Add ArgumentParser
Streamlines parsing of commandline arguments Arguments reside in ProjectSettings as `openvic2/data/arguments` as a dictionary The dictionary's key is the option name The dictionary is set with default values This enables project setting overrides for arguments (user specified arguments take priority) Add help commandline option Prepare for removal of GameDebug.gd Add game project description
