feat: disable datafusion's default features

[valkum]

Closes #48

This disables DataFusion's default features and thus allows downstream users to select which default features in datafusion are enabled in their builds.

Tests in /python appear to succeed, but there aren't a lot. I am also not very familiar with py3 bindings and not sure if all features should be enabled for the python crate.

I haven't checked other dependencies for their default features. geo seems to have multiple default features, one which pulls in rayon, so it might be another candidate for default-features = false.

Thanks!

The top-level Cargo.toml for the Python bindings is here, so this PR doesn't currently change the fact that the Python bindings include DataFusion's default features:

geodatafusion/python/Cargo.toml

Lines 21 to 22 in 79710d3

	datafusion = "50.2"
	datafusion-ffi = "50.2"

I had a look at https://github.com/datafusion-contrib/datafusion-table-providers/blob/main/python/Cargo.toml as a reference, and there it uses the workspace-defined dependency with default features disabled. Should I disable the default feature for the Python bindings as well?

In that case, I don't see why not; might as well try setting default features off and see if it works
