[ROTKR-67] A patrol neural network directs an enemy to search for the player

[hatfield-c]

A neural network should be created which directs enemy ships to patrol in search of the player.

This network should prioritize.

• How quickly it finds the player
• Not bumping into obstacles
• Constant movement (no sitting in place and turning)

[hatfield-c]

The patrol network should have the following characteristics:

Input

• Sphere casts to detect when a player has been seen
• Current speed of the agent (velocity magnitude, normalized with respect to max velocity)
• Current direction of the agent (velocity values normalized)

After conferring with Kevin, we have decided to defer implementation of "search" behavior for now, in lieu of focusing on combat behavior.

Instead, when an enemy ship is spawned, it will immediately chase after and fight the player.
