Cloud-optimized GeoTIFF ... Parallel I/O

Yet another attempt at creating a GeoTIFF reader, in Rust, with Python bindings.

Roadmap

2024 Q1:

• Multi-band reader to ndarray (relying on image-tiff)
• Read from HTTP remote storage (using object-store)

2024 Q2-Q4:

• Integration with xarray as a BackendEntrypoint
• Implement single-band GeoTIFF reader for multiple dtypes (uint/int/float) (based on geotiff crate)

2025 Q1-Q2:

• Support for DLPack protocol (through dlpark)
• Initial release on crates.io and PyPI

2025 Q3-Q4:

• GPU-based decoding (via nvTIFF)
• Asynchronous I/O (refactor to async-tiff)

2026:

• Direct-to-GPU loading
