Extensions

[gadomski]

These are all the stable ones, plus raster:

• [x] Electro-Optical
• [ ] File Info
• [ ] Item Assets Definition
• [ ] Landsat
• [x] Projection
• [ ] Scientific Citation
• [ ] View Geometry
• [x] Raster

One thought here is to include stac_extensions on Asset but exclude it from serde, and then propogate those extensions up/down to the Item. That makes it easier to add an extension to an asset without requiring an associated item.

Implementation begun in https://github.com/stac-utils/stac-rs/pull/234. I'll consider this closed when I have all stable extensions implemented.
