Update pcv.segment_image_series and tutorial

[HaleySchuhl]

Is your feature request related to a problem? Please describe.
We have a temporary workaround for now, but we ought to update pcv.semgent_image_series to handle the v4 syntax of multi-object ROIs (e.g. Objects class).

Describe the solution you'd like

• Update pcv.semgent_image_series to accept the output from pcv.roi.multi in the roi input parameter
• Update the documentation so that it's clear this can be used on one time series at a time
• Update the tutorial here based on the new syntax
• And finally, add the updated tutorial to the PlantCV gallery of tutorials (add all the buttons, and add a link to the tutorial from the function documentation page.

Describe alternatives you've considered
Document the workaround.
