Adding an MAP optimization `EpiMethod`; possibly tempered #306

Following the issues with #238 we could experiment with initialisation of pathfinder.

I've had success with pre-heating the pre-heating of pathfinder but doing a sequence of tempered MAP optimizations to initialize pathfinder, which subsequently gives an informed starting point for NUTS metric selection e.g.

Noting that this could be a fun issue for a new contributor...

Some recent developments: Turing 0.33 has a nicer interface to mode optimization https://turinglang.org/docs/tutorials/docs-17-mode-estimation/ so this should be nicer to do.
