GSoC 2024: Geometry Nodes: File Import Nodes

Week 5

Have been all over the place this week trying to come up with a caching mechanism. In the meantime I decided to knock out the OBJ import node which seemed simple. here is the work in progress PR.

An OBJ file can contain multiple meshes and curves which makes it a bit challenging to output the data from the node, but geometry instances and geometry sets can be used for this.

As for caching I’ll do the simplest thing I can and then go from there based on reviews.
