integration of temporal caching

Mentioned in email chain with @sbna, @ivanspisso David Demarle and @acbauer etc.

From Dave

My changes to update openFOAM for Catalyst v5.9 (at least the recently legacy mode) and adding in the new temporal option are available here: https://github.com/demarle/openfoamvismodule. Also etc/casedicts/insitu/catalyst/printChannels.py needs python3 print()s. As described in the video I just used the propeller tutorial with a fancied up Catalyst script to do OSPRay path traced rendering and the cache-rewind-revise-playback-and-continue trick to exercise all of that beautiful memory capacity. My changes to the case files are attached.

If you attended SC you can see my recorded presentation here: https://www.eventscribe.net/2020/includes/tracking/clickTracking.asp?lfp=R0M2WEp6UWtPdll4czk2T1hSVFlROGUvY2ZWWTFyWklyY2ZacVgrZUk0L2pBTWdPNm1GcmF5NVpGYlpLN2hzRXVZTlo1dVkyam13NGJ0bmVKOUc5dWVyYjEvdlIxdEFpZE02OVA5M2dKUGdVZko1eEQ1SE9semljMVBJVUFCNkNVSlN4VGZnSHlSVkFwNnR4YmZLVEl5YWVKS0NVcTN4YVR1OXU5bzdhWFRYdDlEamF0NWorbkt3WE95MlorTCtzOUp2SGpQWkFwc3FCajlJeTcyU25zZG5RR2NsWXVqdXd3bmtOUXBrTHZNQT0= Otherwise the slides are here: https://drive.google.com/file/d/12ilOYNBfcDYgIaOOfW4eO_o1npAi7Eib/view?usp=sharing
