* this simple implementation works for us because the listbox content
  doesn't change once it's set
* otherwise, the scrollbar causes the listbox to recalculate its size
  requirements on every render, which gets very laggy with many widgets
  in the listbox

* allow marking focussed format as (E)ndangered or (S)afe

* for typing annotations and other goodies

* utilize the new result loading functionality
* use a data structure better suited for the actual operation

* building up this list while loading results reduces the amount of
  potential work for filtering later on
* also enable passing a list of already known formats to
  `load_results(...)`
* new formats will be added to the supplied list as they're encountered

* the initial implementation is limited to only viewing the list of
  formats and listing the files (grouped by records) that use each
  format

* these can happen if the error log file gets closed while the
  subprocesses are still writing to it, which can happen if the user
  aborts the execution with ^C

* this includes marking specific files as "safe"
* it can also be used to override the file format otherwise identified
  by siegfried

* in case the user hits ^C, skip the remaining files and store the
  results so far

* split the code into separate reusable modules
* add config files for linters & formatters
* force the progress bar to update after every sf run
* mask foot terminal as xterm for nicer progressbar output

* to ignore personalized files that would be built up over time by
  formatscaper

* also set it as default, because it's much faster and smaller than yaml

* this should help cut down runtime if there are large files involved
  (especially archives)

* remove the ETA, because that's never accurate anyway

* this is useful to see if the authentication and everything else works

* this is useful for local/development instances that have self-signed
  certificates and thus wouldn't pass the SSL check

* because they're ancient, and InvenioRDM has started providing version
  upgrade guides themselves since v1

* add script for fetching logs from the log server (OS)
* add golang-based program for calculating statistics from logs
* add README with more detailed information
