Update documentation w.r.t. features for the CLI crate

[lnicola]

https://github.com/stac-utils/rustac/tree/main/crates/cli#installation implies that duckdb is an optional feature, but it's not, and it's required to build.

Just to be clear, would you like DuckDB to be optional for the Rust CLI crate or for the Python package?

[lnicola]

The CLI crate, see the linked installation instructions (that I didn't test).

[gadomski]

Is there a reason you don't want DuckDB in the CLI? The CLI is pretty heavy, dependency-wise, as it is ... I'm not sure how much benefit there would be in making it optional. We could just fix the docs to indicate that it's required?

[lnicola]

No, not really. I just wanted a lightweight tool to query STAC and tried to install it from crates.io, which failed. I checked the code and it looks like it could be optional, but if I have to install a new package I might as well go for the Python one (since it's presumably more mature).

[gadomski]

The Python package uses this code, so yeah try python -m pip install rustac and see if that works for you. The install failing is a bug, I'll update this ticket to reflect and look into that. Thanks for the report!

[gadomski]

@lnicola can you re-try your cargo install with the duckdb-bundled feature?

cargo install rustac -F duckdb-bundled

[lnicola]

That compiles fine on my system.

[gadomski]

Awesome! I'll update the docs, thanks for the report.
