 * Very cheap script to convert the jedec database from a text dump of the
 * official PDF to json. The regex abomination below has been kicked until
 * it worked on the version that was current as of April 2019. YMMV.
 * For input, download the PDF from https://www.jedec.org/system/files/docs/JEP106AY.pdf
 * and then copy/paste the contents into a plain text file called 'jedec'
 * (And pray it doesn't break if you don't use exactly the same PDF viewer and
 * text editor as I did - pdf.js and vim)
