GRHayL library inclusion proposal in ET_2023_11
===============================================
* Ticket 2497, as scheduling doesn't mix con2prim and updating Tmunu
* IllinoisGRMHD would no longer see feature updates, be marked as
  deprecated and eventually archived.

  be provided when IllinoisGRMHD is no longer updated. Sam has a draft
  of such a document written already.
* Roland mentioned to carry IllinoisGRMHD along in the ET even after it
  no longer sees updates until maintaining it becomes prohibitive. At
  which point it would move to a archivedthorns-IllinoisGRMHD repository
* this will not affect GiRaFFE
