Fitting dynamic occupancy models with TMB

Following my recent attempt to [fit a HMM model to capture-recapture data with TMB](https://oliviergimenez.github.io/post/multievent_in_tmb/) and the rather estonishing outcome (the code was 300 time faster than the equivalent R code!), I was curious to add TMB to the [list of options I tried to fit dynamic occupancy models](https://oliviergimenez.github.io/post/occupancy_in_admb/). Well, the least I can say is that TMB is fast, damn fast!

Fitting occupancy models in ADMB

Some time ago, a student of mine got stuck when fitting dynamic occupancy models to real data in Jags because of the computational burden.
