Add-ons SVG Template by Xon 2.6.2

Fix "XFCP_TemplaterHelper not found" error when upgrading the StandardLib add-on via the GUI

• If this has happened, upload the files for this add-on. Then rebuild StandardLib add-on, then run the updater this add-on.

• Require XenForo 2.2+
• Require StandardLib v1.11.0+
  • Improve support for rendering templates in the mail & api contexts by correctly injecting template filters/functions into multiple rendering contexts
• Compat fix when zlib output compression is enabled for PHP8.0.17+/PHP8.1.4+

• Work-around for non-desirable caching behaviour when CloudFlare (or similar) is forced to cache svg.php output
  • Prevent polluting of caches if the time-stamp is in the future
