Eco Hero Marie v3

Added a whole new campground area along with some quality of life changes:

• Hold Escape to skip the intro cutscene
• Fixed tree to the south of the starting location that didn't have a hitbox
• Fixed bottom-left area grass not going all the way to the edge of the river
• Replaced the more abrasive bird sounds with two, more chill tracks
• Added a "trunk/boot closing" audio cue for dropping off items
• Slowed down the breathing/idle animation a bit

The game probably needs another one or two levels, along with some kind of transition or driving sequence.
