When enabled entries in the DB are stored as base64
encoded xz data. To uncompress save to a file
my_json.base64 and run:
cat my_json.base64 | base64 --decode | unxz --decompress - > my_json.txt
This allows users to specify the minimum wait for each
request. The (currently wrong) estimate of
retry_after / rate_limit is calculated, and the max
between that and the setting in the config file is
used.
