Add enemy missle projectiles for wave 3 with new sound effect and updated shooting logic 

This commit implements enemy missle projectiles for wave 3 enemies, including:
- Added new 'missle' audio file and loaded it in GameScene
- Created enemyMissles physics group for tracking missle projectiles
- Updated game waves configuration to include wave 3 with special enemies (texture 3)
- Modified enemy spawning logic to handle missle capability for wave 3 enemies
- Implemented enemyMissle() method that creates two directional missles that later home in on player
- Adjusted enemy shooting logic to differentiate between regular bullets and missles based on texture
- Added collision detection between player and missles
- Updated wave-specific properties handling for new enemy types

The changes enable a new challenging gameplay element in wave 3 where enemies can launch homing missle projectiles.
