chore: wrap_comments = true

[obycode]

I opened this so we could take a look at the results and discuss if we want to do something more consistent than what we do currently. It is not smart enough to just merge this PR unfortunately, as it does some dumb things with spacing.

The problem I am trying to solve is that some places we wrap at column 80, some wrap at 100, some at 120, some never. There is not much consistency.

A couple comments:

• I think we should set comment_width to greater than 80 (like 120?). We have plenty of lines of code longer than 80 chars, and it would result in a smaller diff
• This should be set in rustfmt.toml. The fmt-stacks alias only exists because those specific options only work from the command line
