Add method to specify events to run on the map

[keyz182]

Add a flexible system for defining and triggering events on the map, allowing for more variety and customization.

Goals:

• Fixed Events: Guarantee that specific events occur at designated times or locations on the map.
• Random Events: Implement a system for randomly choosing and triggering events from a pool of possibilities.
• Delayed Events: Allow for events that occur after a certain number of in-game ticks or meet specific conditions.

Implementation Notes:

• Event Triggering:
  • Implement mechanisms for checking trigger conditions and initiating events.
  • Use randomness for random events and timers/counters for delayed events.

Example Events:

• Fixed: Boss encounter after clearing a specific area.
• Random: A trader arrives with rare goods.
• Delayed: A wave of enemies spawns after 5 minutes.

Additional Considerations:

• Event Chaining: Allow events to trigger other events, creating more complex scenarios.
• Weighting: Give different events different probabilities of occurring for random events.
