New contrib extension - Sortable Tables Macro

The sortable tables macro is neither new nor high maintenance, but by popular demand :wink: I have been asked to make it available via contrib. So here it goes:

  • Name: macro-sortedtables
  • Jira: MST (because who does not love TLAs)

I can set up the github repo and JIRA project myself, just wait a moment to get feedback on the names.
