Question about the new hidden Markov modeling functionality in `hmm_marginal`

, `hmm_hidden_state_rng`

, and `hmm_hidden_state_prob`

: are time varying state transition probability matrices supported?

The use cases that I have in mind are hidden Markov models in ecology (e.g., for animal behavioral states, occupancy states, live/dead, infected/uninfected states), which model transition probabilities as a function of time varying explanatory variables.

Thanks!
