add number to pages

[rettinghaus]

It would be nice to have @n attributes on <pb> (for working manually with the file).

In practice, this tool is used pretty often for scores that do not start on page 1. Therefore I would prefer to keep it as is to avoid manual corrections.

Adding the @n attribute, however, should be fairy simple: Add a counter before line 202 in App.vue and keep track of it inside the forEach loop.

If I find some time, I will add an option pane for things like this in the future.

Hmm, after thinking about it some more, we also have automatic measure numbering which oftentimes is off by a certain offset. Removing such numbers is less work than adding them, so I will look into it later today.
