Feat: Add sound effects for the trains

[mathieucaroff]

First, thank you for making that game rip-off, it's nice to be able to play ToT at any time.

I would like to have sound effects in the game ; I find it's really lacking.

In particular, I'd like to have:

• A sound for when a dot-train reaches the right square-station
• A sound for when it reaches the wrong square-station

There's also the possibility of adding a sound effect for when a new dot-train enters the game or one for while the dot-trains are running.

I've found the following basic sound effects:

• Two error sounds:

• A few validation sounds:

• Phone UI sounds may work: https://www.zapsplat.com/sound-effect-category/button-clicks/
• Or maybe bell sounds: https://www.zapsplat.com/sound-effect-category/bells/

I've also found train-related sound effects:

• Another running train: https://pixabay.com/sound-effects/train-railroad-traffic-sound-8002/
• A running train sound: https://freesound.org/people/InspectorJ/sounds/332014/

Have a good day!

Hi, thanks for providing all those sounds:) I will try working on it once I have some time

I've been thinking; having a clicking sound for the rail switches would be great too.
