Separate Analog and Digital data streams

[bparks13]

Instead of using the AuxiliaryIO device to combine the digital data as a TTL on top of the AnalogIO data, create the DigitalIO data as a separate data stream that saves its own timestamps. Test this to see if data is now aligned.

Outstanding Questions:

• Should this include going back to using two tabs for the two streams? Currently they are both under the AuxiliaryIO tab, but we could easily separate them out into a AnalogIO and DigitalIO tabs, but I'm not sure if it is worth it.
• Should users be able to disable the digital/analog data streams independently of each other?

@jonnew @aacuevas Another question that came up while I was working on this; should we add the events of the digital data on top of the continuous data stream? I know that this creates redundant information, but it allows the events to still be available in the plugin, and for downstream plugins, while ensuring that they are added at the correct timestamp.

• I think its not worth it to separate them and I kind of like that they are together
• I would add the events so long as they can carry the timestamp because thats the only way of knowing when the happen. Can the user save events and not save the continuous data. if so that would be nice.
• I think we can leave enables as is, its not that much data in the grand scheme of things.

If we add the events at the same time as the continuous data it will be at the correct timestamp, and the timestamps are saved with the events. As far as I know there is no way to save events without continuous data, so there is some redundancy there.

of course not. ok whatever, good enough.
