+Hacky script that parses PROTON_LOG=+fsync,+microsecs and emits wait-states in VKD3D_QUEUE_PROFILE format with VKD3D_QUEUE_PROFILE_ABSOLUTE=1.
+Equivalent in more plain Wine would be WINEDEBUG=+fsync,+timestamp,+pid,+tid,+threadname,+microsecs WINEFSYNC=1.
+Can be used to directly append to vkd3d-proton generated JSON.
