properly implemented seeding for BinaryFOVSensor (probably)

[kenblu24]

I didn't update BinaryFOVSensor to use the new seeding system back when I introduced in 6f0ab4c.

Now, BinaryFOVSensor should attempt to seed its own RNG in this order:

1. seed arg in BinaryFOVSensor.__init__() (or seed in yaml config)
2. BinaryFOVSensor.parent.rng
3. BinaryFOVSensor.agent.rng
4. System time (np.random.default_rng(None))

BinaryFOVSensor.rng is now the rng that should be used within the class/instance, rather than RandomState np.random.random which is now deprecated.

Pull Request Overview

This PR implements proper seeding for the BinaryFOVSensor class to align with a new seeding system introduced in a previous commit. The changes establish a consistent RNG hierarchy where sensors can inherit random number generators from their parent or agent, falling back to system time if neither is available.

• Updates BinaryFOVSensor to use the new seeding system by passing seed parameter to parent constructor
• Replaces deprecated numpy RandomState calls with modern Generator API
• Adds seeding infrastructure to AbstractSensor base class with fallback hierarchy
