2 port over relevant material from main workshop

[davecash75]

The first five episodes for hour 1. THe first three will take up the first half hour (or hopefully less) and the next two will take a little longer.
I've added a fair amout of instructor notes fenced divs to help me know what areas to skip.
I've also ported two episodes in the learners area for links to work and also for additional background.

What does this mean?

If you have source files that require output and figures to be generated (e.g. R Markdown), then it is important to make sure the generated figures and output are reproducible.

This output provides a way for you to inspect the output in a diff-friendly manner so that it's easy to see the changes that occur due to new software versions or randomisation.

Yes. Looks good.

I like that you have split the napari-notebook from the instance segmentation lesson. Something to consider doing for HealthBioscienceIDEAS/microscopy-novice too.
