Updating an episode to make a better starting point

[brownsarahm]

a PR was submitted to mark an episode as avoid for demos because it had a very small dependency on the previous episode, instead of accepting that, I proposed to the lesson maintainers that we add the code (2 lines) to the episode to remove the dependency.

The maintainer recommended using a .prereq box with an explanation of when those lines are/not needed.

Sharing here in case it's helpful for others.

> ## Episode Prerequisites
>
> If you are continuing in the same notebook from the previous episode, you already
> have a `data` variable and have imported `numpy`.  If you are starting a new 
> notebook at this point, you need the following two lines:
>
> ~~~
> import numpy
> data = numpy.loadtxt(fname='inflammation-01.csv', delimiter=',')
> ~~~
> {: .language-python}
{: .prereq}

@carpentries/core-team-curriculum this might be relevant as you all will be helping with starting point maintenance more generally across all lessons.

Thank you @brownsarahm. The Curriculum Team has reviewed this conversation and agrees that this is a good fix!
