This is an internal function that generates a new dataset given the inputs

1	simulate_dataset_PPP(n, n_t, gamma, mu, eps, zeta, Q, seed)

`n`	int. number of subjects.
`n_t`	int. number of observations for each subject.
`gamma`	vector of length m times m containing transition probabilities.
`mu`	vector of length m times m with emission distribution means.
`eps`	vector of length m times m with residual variances.
`zeta`	vector of floats. between-subject variance of the emission distributions.
`Q`	float. between-subject variance of the transition probability matrix.
`seed`	int. random seed used to generate the dataset.
