Add trame to the superbuild
Filing here instead of the superbuild for easier project management purposes.
The current plan:
- use a venv (or equivalent) to manage trame with ParaView 5.11
Future ideas (tentative 5.12):
- have an option for "latest" trame for development/deployment test purposes
- add trame to the superbuild with an option for "some specific version" to ship with ParaView itself (probably cannot update external however); this would pin "latest" as of tagging and/or testing checkpoints
