  - add sanity_check
  - add update_config_sizes

Init Script:
  - a lot of visual output improvements, especially with verbosity=2
  - better output separation for different verbosity levels
  - removed unneeded runningErrorFile

  - added functionality to throw warnings if TLDs or leading-dot domains are discovered
    in the final block-list file (can be disabled by `sanity_check` option)
  - added functionality to test DNS resolution after resolver restart with `heartbeat_domain`
    for `heartbeat_sleep_timeout` seconds
  - added functionality to revert the resolver's config/ad-blocking if heartbeat domain cannot
    be resolved after resolver restart
  - added `ALLOWED_TMP` variable/file for better processing of external allow-lists
  - added debug output to log with the elapsed time for each step of processing
