Issue scaling scores

[benory]

It would be good to be able to make condensed/smaller PDFs of individual scores. For Willaert's Verbum bonum, using the option evenNoteSpacing condenses the outputted PDF to 11 pages.

Some possible options to help with this:

• scaleToPageSize
• scale (this does not seem to be working appropriately)

Verovio's documentation indicates that the value after the scale option should be an integer, with a default of 100.

A PDF of roughly seven or eight pages would be ideal.
