A base class that send DMX data asynchronously to a libusb_device.
This encapsulates much of the asynchronous libusb logic. Subclasses should implement the SetupHandle() and PerformTransfer() methods.

This method is implemented by the subclass. The subclass should call FillControlTransfer() / FillBulkTransfer() as appropriate and then call SubmitTransfer().

Called when the transfer completes.
Some devices require multiple transfers per DMX frame. This provides a hook for continuation.
