change config template to match use of jsons for preprocessed semantic files
use jsons to store intermediate keyword files, corrects use of filenames depending on subdirectory, and merge keyword files to create other dict files
read jsons instead of pickles
add folders to script for test purposes (testset with multiple folders but few files available from me)
