Consolidate dependencies in workspace

[nyurik]

Currently there are some dependencies that are in the workspace, while others are scattered all over the individual Cargo.toml files. This results in some dependencies using different versions. I would like to move all dependencies to the root workspace Cargo.toml, and referencing them from one place.

• if any crate needs no-default, than the workspace cargo.toml would listed as such, and users could add default back with features = [default]
• if different features are needed by different crates, either the common set is added to the workspace, or specific features can be used by the using crate
• dependencies that are part of this repo would be used the same as any other - with the path being listed only in the workspace one

I can do this refactoring if ok with maintainers
