Muse Dash: Update songs to 4.2.0. Add a new trap.

[DeamonHunter]

What is this fixing or adding?

Updates the song list to Muse Dash 4.2.0. Also adds a trap using the new VFX that came with the update.

Note: Might conflict a bit with #2809 but will be an easy resolve.

How was this tested?

Using tests and a test generation.

I think the newline somehow got eaten?

It's still there, Github hides it by default and instead shows a no symbol if the newline isn't present.
