This PR gets rid of a number of mostly similar methods (with slightly different behavior for explorer vs mda):
and replaces them with two functions:
_determine_sequence_layers
- a pure stateless function (i.e. not a class method) that takes asequence
object, and returns information(id, shape, metadata)
about all of the layers that need to be created for the experiment (based on whether C or P is being split. Being stateless is particularly nice here, since it means it can be tested completely in absence of a core, a widget, a viewer, etc... (but that will happen in a followup PR)_create_empty_image_layer
- one method that creates the necessary layers.
