Font data may write before chars parsed

[Anatoly Korablev]

fontFile.data = utils.stringify(fontData, outputType);
may happens before
const asyncTextures = await Promise.all(textures);
So chars data may be empty.

It's happens for me when i try to reuse texture for another font. My solution is to move first line after second.

I'm looking for the missing chars data right now.
