Give Circuit Demultiplexers memory

[Menroka]

Right now it is very hard, if not impossible, to use Demultiplexers, because every time you pule it and write something to the selected output, all other outputs get set to null.

So every circuit that comes after the demultiplexer needs to verify, that the input data is not null, before accepting the potentially new data, or it just doesn't work.

You should be able to tell it which address to write to and it writes to that address and doesn't change any of the others. That way you can have every output set to something and only change the one you want to change.

Alternatively, if there is actually a use-case, that requires this behaviour, I would like to request new memory bank items, that function exactly as described. Making something like a circular buffer is otherwise just a massive headache, because you need to reroute the memory output back to its input, but only if the demultiplexer is null. This is too much effort for something that should be a standard part.

I can do that, make an extra pin that toggles the behavior between this and the old way.
