USAGE: convert-nei-dump <source> <target>

    Converts output from NEI dump files into a format which can be used by
    Crafting Guide. In particlar, this script looks for the "Item Panel" dump
    both in PNG and CSV formats and assumes they contain all the data for the
    target mod.

    Unfortunate, NEI doesn't generate enough information to fill in all the
    recipes for each item: only their names. Once this script has converted the
    data, you will need to manually enter the missing content.

    <source>    :    the "dumps" directory where NEI dropped its content
    <target>    :    the mod version directory where the finished files should
                     be placed
