dynamite version 1.3.0

• Added support for Student's t-distribution via "student" family in obs().
• Added support for the multinomial distribution via "multinomial" family in obs(). A trials() term is now mandatory for multinomial channels.
• The generated Stan code now automatically switches between the array keyword syntax and the deprecated syntax based on the backend Stan version (see https://mc-stan.org/docs/reference-manual/brackets-array-syntax.html for details).
• The presence of variables used in trials() and offset() is now properly checked in the data.
• The model components trials() and offset() now function correctly in predict() when they contain response variables of the model.
• Fixed the calculation of the number of observations in nobs() for models that have multivariate channels.
• Fixed an issue in predict() with models that contained multivariate channels with random effects.
• Scenarios that have zero non-missing observations at specific time indices are now handled properly in the Stan code generation.
• The names of additional arguments passed to rstan::sampling() and the sample() method of the cmdstanr Stan model via ... in the call to dynamite are now checked and unrecognized arguments will be ignored.
• Added a new function get_parameter_dims() that returns the parameter dimensions of the Stan model for "dynamitefit" and "dynamiteformula" objects.
• Group-level random effects are now supported also for categorical and multinomial channels.
• Added a new vignette that describes how the package can be used to simulate data from a dynamic multivariate panel model.
• Added a new vignette that describes how the default priors of the model parameters are defined.
