All dependencies that are dependencies of multiple crates within the
workspace were pulled up to the root `Cargo.toml`. Dependencies that are
dependencies of just one crate within the workspace remain in the
`*/Cargo.toml` of that particular crate.
Generally, this helps us keep an overview of dependencies:
- If multiple crates depend on a crate, we will see the reference to
the workspce.
- Otherwise, we will see a line that specifies the version.
It is up to the maintainers to recognize when a dependency becomes a
dependency of multiple crates in the workspace, at which point it should
be moved to the workspace.
The tool `cargo-autoinherit` can be used to automatically pull *ALL*
dependencies to the workspace. I used this, and in a separate, manual
step, filtered out those dependencies that are dependencies of a single
crate only, moving those back manually.
At the same time, I also unified depending on sibling crates in the
workspace. This is now also done via workspace dependencies.

This declares the minimum supported Rust version, independently of the
`rust-toolchain.toml` file, which specifies the Rust version and
toolchain components the crate/workspace should be built with. The
MSRV affects other crates that depend on anything in this workspace,
but the toolchain file does not seem to affect them. This means the
MSRV is useful for those who build or develop dependents.
