This is a quick fix for #24. Since PIO and SIO can't share GPIO access, we need to reconfigure pins when switching between manual and buffered execution. A proper fix would be moving manual updates to the PIO, but because the prawnblaster insists on the outputs being low at start and end of execution anyway, we can tolerate a single reconfigure when switching between manual and buffered.
This change caches if the SIO has already reconfigured the GPIO. If it has, it skips reconfigure.
