Clean up dependencies.

[mikebenfield]

Remove unused deps. Use workspace deps where appropriate.

Do you forsee any issues with maintainability by moving all of these workspace dependencies? Curious, does it reduce build time?

[mikebenfield]

I doubt it reduces build times generally. Maybe in some weird cases where some crates were getting redundantly built multiple times? Not sure.

IMO the main advantage is just keeping the versions and feature flags in one place. We bump the version of Leo or a dependency, we don't have to search across a ton of different Cargo.toml files to make changes.

Does the workspace dependency for indexmap need the serde-1 feature?

[mikebenfield]

My understanding from reading indexmap docs is that serde-1 is sort of deprecated now, and instead we're supposed to use serde.

These release notes mention serde-1 being removed (although for a later version than we're using)

[d0cd]

Let's upgrade to 2.0.0 and use serde.

[mikebenfield]

I switched the remove calls to remove_shift, as discussed, although that does potentially change behavior.

LGTM!
