Maintenance/print width

either tiny or the largest ever

@frasercl proposed that the formatter printWidth be bumped from 80 to 120

That's a one line change.

However, it means that every time a file gets edited in the future, that PR is likely to contain extra formatting changes. We could just do it all at once instead.

So I ran prettier --write "." to format the whole repo with the new rule, that's why this PR is:
19,885 additions and 8,319 deletions

Either we trust that these are just formatting changes and assume that: printWidth: 120 is the only piece that needs real review, or I will do a different PR with only the config change, and we can let the process of reformatting the repo happen gradually over time. Thoughts?
