registerAFMFonts not using default Helvetica font exports

[jarommadsen]

I was running into the same errors as this issue and was particularly confused about this error:

Uncaught (in promise) TypeError: Cannot read property 'split' of undefined
    at new AFMFont (pdfkit.es5.js:2453)
    at new StandardFont (pdfkit.es5.js:2700)
    at Function.open (pdfkit.es5.js:3096)
    at PDFDocument.font (pdfkit.es5.js:3170)
    at PDFDocument.initFonts (pdfkit.es5.js:3132)
    at new PDFDocument (pdfkit.es5.js:4890)
    at new PDFBuilder (PDFBuilder.js:42)
    at PDFCreator.createID (index.jsx:40)
    at PDFCreator.componentDidMount (index.jsx:72)

The proposed workaround was to do a direct import from raw-loader:

import Helvetica from '!!raw-loader!pdfkit/js/data/Helvetica.afm'

This was strange to me as removing the !!raw-loader! portion still seemed to work and furthermore adding !!raw-loader! to the require.context call did not fix the error.

Turns out you just needed to use the default export of the files to avoid the error:

fs.writeFileSync(`data/${match[0]}`, ctx(key).default);

Not sure if this was a pdfkit update or what but it'd be good to update that line.

The raw-loader changed how data is exported see: webpack-contrib/raw-loader#69

I updated the code accordingly
