Issue_6456 Using # in links causes errors in PDF generation

- The # sign in an URL needs to be escaped as longtabu reads the table body as the argument to a command, so the self-escaping mechanism of \href cannot work (from https://tex.stackexchange.com/questions/447461/having-a-hash-sign-in-href-in-a-longtabu-cell)
- a regression regarding the change from `\tt` to `\texttt` (needed `{  ... }` as `\href` has 2 arguments )
