Chris Hill-Scott d0f90eac7e Add an endpoint for generating a PDF of a letter ...

Previewing a letter is different to previewing an email or text message
because:

- a letter has a layout
- the layout is fixed, ie it doesn’t depend on the user’s device
- the ‘send yourself a test’ feature won’t be as useful because it has
  a lead time, so the feedback loop will be much longer

For these reasons a HTML-only preview of the letter won’t be enough (we
don’t think). A PDF is more appropriate because:

- it can replicate the layout of the letter exactly
- it is a print format, so the user could even print themselves a copy
  locally to get a feel for how it will look

This commit makes use of Flask WeasyPrint [1] to take a HTML
representation of the letter, convert it to a PDF and serve it back to
the user.

The actual work to generate the HTML and specify the layout is done in
utils, same as we do for rendering other messages.
