accessibilityMap: v1 had an accessibleNodes parameter we could pass to restrict analyzed data

[tahini]

This parameter was used in Transition's genetic algorithm to cache the accessible nodes from a place, in the accessibility indicator. It would speed up the tests.

Do we need/want to implement this again? Is this still an issue in simulations?

Keeping this as a not here to consider the question at some point.

Some of that code was removed in 56e23ab
