FinalizeLink Action that runs when Acquisition stops or fails

[jonnew]

I think it would be beneficial to have a Finally() operator that turns the port voltage off when acquisition stops. My understanding is that all Actions and Functions gathered by Configure<thing>.cs nodes are executed by context.Configure() at line 23 of StartAcquisition:

https://github.com/neurogears/onix-refactor/blob/69c0d3546fb9eae5565a370fb7cfe9b182c06475/OpenEphys.Onix/OpenEphys.Onix/StartAcquisition.cs#L23

I think this sequence would need to have a Finally() appended to it, and Configure<thing>.cs nodes should have the ability to register a FinalizeLink Action that is executed in the Finally() operator appended to the StartAcqusition's observable sequence.

@glopesdev I remember that this may have been implemented in a branch, but I can't seem to find it. Let me know if I'm mistaken
