Added to the SVG converting script a line to create .svg.js files.
These files are normal JS files that exports just a single string,
the SVG file content. This way the library doesn't need a build
step to embed these files and/or node:fs to read them.
Orgnanized the banners in the design file, now each is
on a different page/canvas. This also fixes the exported
SVGs having the other banners code in them.
These files will be converted to standard SVG files using a script.
So things like Inkscape's labels can be converted to IDs (because
Inkscape doesn't support duplicated IDs on the design.inkscape.svg
file).
