Add option for penalized likelihood to occuMulti #209

Also implements a K-fold cross-validation based approach to finding the optimal penalty term value. Separation and boundary estimates are fairly common issues with occuMulti so this should be pretty widely useful.

Based on the following paper in press:

Clipp, H. L., Evans, A., Kessinger, B. E., Kellner, K. F., and C. T. Rota. 2021. A penalized likelihood for multi-species occupancy models improves predictions of species interactions. Ecology.
