dynamite version 1.2.0

• Added support for the multivariate gaussian distribution via "mvgaussian" family in obs. See the documentation of dynamiteformula for details on how to define multivariate channels.
• Latent factors were not previously used in predict by error, this is now fixed. However, due to identifiability constraints no new group levels are allowed with models using latent factors.
• Response variable names of the channels are now processed to avoid invalid variable names in the generated Stan code. Note that these variables names should be used when defining priors and when using methods of the dynamitefit class. You can use the functions get_priors and get_parameter_names to see the names that are available, as before.
• Optimized prediction code by removing redundant expressions and using better indexing.
