filename: ./data/yourdatabase.csv
	delimiter: ; --> if the value is comma ',' better wrap it with quotes
	outputdir: ./html/output
	deepdirs: 3 --> this will create a structure of directories of N deep
	max_threads: 150 --> max workers to deal with file creation
	pbkdf2_iterations: 1000 --> the derived key is using pbkdf2 algorith, then, we need some iterations 
	pbkdf2_keylength: 32 
	hash_dir: false --> if you want to apply a pbkdf2 derivation to the folder tree created from the first N chars of filenames

	colums_hash: 1,2 --> colums from the csv to perform the hashing
	columns_content: 3,4 --> columns from the csv to put in the hashed file. It could be a negative integer, then, all the columns from the positive integer will be added to the content of the hashed file. E.g. -3 will add all columns from the 3rd to the end.
