Add NeuralynxSortingInterface

[garrettmflynn]

This PR adds the NeuralynxSortingInterface to the allowed interfaces. However, this currently fails on the test data with the following error when attempting to create a stub preview:

Ah, I see why this is. We don't test if that interface on that data works in sub mode

It's the subsetting of the spike trains that's causing the problem, because this is the first case of it being used on multi-segment data

Will require NeuroConv fix in that case - tabling for now
