Pedestrian Nav Example Ported from FLAMEGPU 1

Visualisation is limited to features of native FLAMEGPU 2 visualiser, and hence (currently) lacks the ability to:
* Hide a subset of agents in the same state (in this case navmap arrows with no force)
* Control environment properties via UI elements
* Control visualisation of agents via UI elements
