Add old blog posts

Closes #18

Work in progress, just adding so no one tries to duplicate the effort 🙈

Using https://mixmark-io.github.io/turndown/ to covert the HTML to Markdown.

Instead of duplicating the hardware.jl post, does it make sense to link to https://viralinstruction.com/posts/hardware/ ? (or perhaps this alternate URL whose domain less likely to expire: jakobnissen.github.io/posts/hardware) It's likely I'll update the notebook in the future, and then it'll be a hassle to also update it here.
In case I go AWOL in the future and my website expires, then you can easily reconstruct the page from the linked-to GitHub page.

I think it should be a canonical_url

<link rel="canonical" href="jakobnissen.github.io/posts/hardware" />

I wish Pluto could would support output to markdown 😞

I think we should move it over to markdown, so it fits with the other posts, and if it doesn't get updated, we can cross that bridge later. Just wanted to check with you before I started copying and pasting.

I think makes sense for now. Cross ref tlienart/Franklin.jl#813
