Load a bank asynchronously (from in-memory data, in-place).
IMPORTANT: Banks loaded from memory with in-place data MUST be unloaded using the UnloadBank function providing the same memory pointer. Make sure you are using the correct UnloadBank(...) overload
Use this overload when you want to manage I/O on your side. Load the bank file in a buffer and pass its address to the sound engine. In-memory loading is in-place: *** the memory must be valid until the bank is unloaded. *** A bank load request will be posted to the Bank Manager consumer thread. The function returns immediately.
