Release 3.12

• Compatibility with Python 3.10
  Note that it is expected that this is one of the last releases that supports Python 3.6.
• Export of statistics as LaTex commands in table-generator:
  All those values that exist in the statistics table on the Summary tab of our HTML tables can be exported as a series of LaTeX commands with --format=statistics-tex.
  These can then be included in a paper and the commands can be used to retrieve the statistics values (documentation).
  The script contrib/statistics-tex.py that provided a subset of this functionality so far is removed.
  Thanks to @Sowasvonbot for implementing this!
• Slight improvements for mounting overlayfs:
  • Avoid redundant mount points that could prevent certain nested mounts.
  • Avoid a warning in the kernel log.
• Fix handling of non-printable characters in environment variables.
• Slight improvements for the HTML tables:
  • Use of color for categories in filters
  • More informative tooltip in quantile plots (thanks @leventeBajczi)
• Added and improved tool-info modules
