Unified MCXD frontend repo #13
Description
Currently, there is a lot of duplication between MC3D and MC2D (https://github.com/materialscloud-org/discover-mc2d-react). It probably makes sense to merge these two repositories.
Github pages doesn't allow to publish two pages for a monorepo, but Cloudflare pages seems to allow this. Also a good option seems to be to use npm workspaces.
This monorepo should also include the shared dependencies such as https://github.com/materialscloud-org/mc-react-ptable-materials-grid
