Added Heavy Attack (Combo 1)

• When the player successfully inputs the keys for Combo 1, a heavy attack launches.
• The heavy attack is larger than a basic attack but moves slower.
• Currently, heavy attacks deal 15 damage to the bus. 

Tweaks and Adjustments

• Boss projectile patterns were changed
  • Projectiles no longer spawn randomly. Instead, they are all generated from the same point. 
  • Projectiles now have smarter pathing and move towards the player, instead of just moving forward. This makes it harder to dodge.
• Added different materials for the boss attacks, Lucy's basic attacks, and Lucy's heavy attack. This was for visual clarity.
• Adjusted Lucy's basic attack damage from 5 --> 2.
• Changed wait time of Bus charge attack from 1 second to 1 beat. This was a practical change to ensure the bus charge attack would also be coordinated with the song. 
• Organized BossAttacks.cs and Inputs_Lucy_Test.cs scripts for clarity. This is because these scripts are particularly lengthy and is becoming increasingly difficult to navigate. Added comments to the majority of the code to explain what they do. 
• Adjusted height of playerAttackSpawn and bossAttackSpawn game objects so that the projectile trajectory was not so close to the floor, which was causing issues with premature collision with the floor. 
• Removed line of code that caused the TimeScale to be set to 0 when "P" was pressed, effectively pausing the entire game but leaving no option to unpause the game. A more comprehensive pause function will be added in the future. 

Bug Fixes

• Fixed an issue with the boundaries that was allowing Lucy to run out of the play area. 
• Fixed an issue where the new imported bus model was not rotating properly when preparing to use the charge attack.
