More data from SongOverlay module

[thijnmens]

I've made an overlay for beatsaber using the SongOverlay module, but the data it sends is quite limited compared to other data mods.

The data I wish to get is the per-saber accuracy that mods like BeatSaviorData and BeatLeader already gather (the number in the circles)

Neither SongOverlay or Datapuller send this information, and since i'm already using beatsaberplus for the other modules i might as well request it here instead of datapuller (which already sends more data). I tried cloning the repository to do it myself but getting it to build is already a hassle (are there setup instructions somewhere?).
