/*
This example script reads live slp files from a folder, and writes
the players stock count and percentages to a file.

NOTE: Please don't actually do this for real custom HUDs. Writing to files is
slow and OBS takes a long time to update after file changes. If you actually
want to build a custom HUD for OBS you should use a browser source and send
updates using websockets instead of writing data to a file.
