feat: More sockets, nodes, fixes.

We're starting to have a very advanced socket-based language
for defining nodes. It's very practical already.

The priorities are
1. All the nodes!
2. Sockets, including default values, as needed.
3. Library constants, mediums.
4. Output socket previews w/geonodes, geonodes structures.
5. Utilities including arrays (and selected array multi-input)

The code is still very spaghetti. This is very much still the
"first, make it run" part of the system design.
