Adds a custom heist track for Hakos Baelz's song "PLAY DICE!", including BGM by DOVA-SYNDROME she has used for stream BGM for stealth and control phases. Stealth: [ひょっこりミーくん - DOVA-SYNDROME](https://www.youtube.com/watch?v=rORdNkcPNvU)  Control: [キュートなマジック！ - DOVA-SYNDROME](https://www.youtube.com/watch?v=H-kYxM6d2nk)  Anticipation/Assault: [PLAY DICE! - Hakos Baelz](https://www.youtube.com/watch?v=na6bysYNuS0)  There are two variations of the Assault track, with and without vocals. It is currently weighted to be slightly more likely to play the instrumental version of "PLAY DICE!", but feel free to modify the `main.xml` as you'd like.
