SVG files that cause non-successful font build when using glyf_colr_0/glyf_colr_1 color format

Not entirely sure what causes nanoemoji to error when building the font. Could maybe be something that Adobe Illustrator and Inkscape add some kind of data that nanoemoji doesn't seem to understand but other glyph font generators have no problem with.

Despite trying to get logging I'm only greeted with the following and I can't really seem to get actual logging out of the Ninja build process.

Traceback (most recent call last):

I've attached a couple of example files that cause the exceptions. Would be nice if the issue could be looked into and subsequently a new release can be published to pypi. Surprisingly CBDT works (as that's the only other thing Chrome/Electron supports) but it's just not sharp enough since it's bitmap graphics. Haven't tested the other color format modes though.
