Support for External Data Sources

[priethor]

SCF does not currently support external data sources with Custom Post Type fields. This project aims to explore connecting SCF fields to external data sources, integrating the Remote Data Blocks plugin, to allow richer and more dynamic content experiences.

Note that Remote Data Blocks takes advantage of Block Bindings and it's focused on blocks, whereas SCF relies on post meta, so the idea is to go full circle so that block bindings and post meta can have a similar level of support for external data sources. Let's consider these scenarios:

• Block binding with external data sources. This is the focus of Remote Data Blocks.
• Block binding to SCF fields. This is in the scope of SCF.
• Block binding to SCF fields from external data sources. This is the scope of this issue.

Note that there are currently limitations on which blocks support bindings in core (e.g. table block is a popular block that doesn't).
