Replace use of rowsums in tidyr episode

[jessesadler]

Close #531

• Use grouped mutate() instead of rowSums() to create summary columns. This is more in line with tidyverse usage and fixes a mistake in lesson where no household was shown to have 0 items.
• Explain use of grouped mutate() and dplyr if_else() function.
• Create new exercise to do the same with months lacking food.
• Remove exercise in pivot longer that replicated earlier calculations in a confusing manner.
• Change code to recreate interviews_plotting in ggplot2 episode using new method.
• Change interviews_plotting data using new method.

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.
