added option to generate soldering help without supplier codes

[npsm]

I liked the script but didn't have all the supplier fields setup for all parts and don't need them for most basic components so I added to option to generate just based on footprint and in the case of Resisters Capacitors and Inductors (R, C or L) footprint + value. option '--include-parts-without-supplier'

Additionaly I added the option '--fill-page' which calculates the label size based on the number off labels per page.

I don't actually print the sticker but just display them on a tabler while soldering, this speeds op placement a lot as it clearly indicates which parts go where.

Hope this is useful for others.

btw. I don't like python and ain't good at it so there probably is a cleaner method of implementing these features.

You should probably avoid altering the default numbers of labels without changing the text stating what sort of label sheet the defaults are set for.
