Since #416, we have first read all Unicode punctuation characters to a table punctuation, then defined parsers.punctuation using the table punctuation, and then we deleted the table punctuation. Since #416, we have also been experiencing steady out-of-memory issues with our capybara runner, as discussed with @TeXhackse earlier today.

I have disabled capybara, since it's been having intermittent out-of-memory issues ever since Markdown 3.0.0 and its speed has also lately been an issue. Nevertheless, this indicates a potential cost of the current approach, which may eventually impact our users as well.

This PR removes the table punctuation directly from the file UnicodeData.txt without any intermediate data structure. This should alleviate any memory issues caused by #416.

Since #416, we have first read all Unicode punctuation characters to a
table `punctuation`, then defined `parsers.punctuation` using the table
`punctuation`, and then we deleted the table `punctuation`. Since #416,
we have also been experiencing steady out-of-memory issues with our
capybara runner, as discussed with @TeXhackse earlier today.
