Function b3RecPlayer_Create 

pub unsafe extern "C" fn b3RecPlayer_Create(
    data: *const c_void,
    size: c_int,
    workerCount: c_int,
) -> *mut b3RecPlayer

Create a player over a recording. Owns a private copy of the bytes. @param data pointer to recording bytes @param size byte count of the recording @param workerCount worker count for the replay world; pass 1 to match a serial recording. Replaying at a different count re-partitions the constraint graph, so the StateHash check becomes a cross-thread determinism test. Adjustable later with b3RecPlayer_SetWorkerCount. @return a new player, or NULL on bad header or deserialization failure
