Added `compose_spec` dependency, temporarily using the git repository.

Also updated some error messages and error docs for
`cli::compose::from_file_or_stdin()`, `cli::compose::from_stdin()`,
and `cli::Commands::try_into_files()`.

Required for converting `compose_spec::service::Dependency`.

Check each field instead of comparing to the default.

Changed `cli::Commands::try_into_files()` to use `compose_spec::Compose`
for conversion to `quadlet::File`s. Now rejects `include` and `configs`,
and requires `secrets` to be external.

Changed `cli::compose::try_into_quadlet_files()` to use
`compose_spec::Compose` and added error docs. `cli::compose::services()`
was removed as it is no longer needed.

Changed `cli::compose::service_try_into_quadlet_file()` to use
`compose_spec::Service` and added more docs. Instead of going through
`cli::PodmanCommands`, the service is converted into a `cli::Container`
directly and then into a `quadlet::Container`. The `cli::Service` is
created from the `compose_spec::service::Restart`.

Removed `cli::ComposeService` as `.volume` is now added to the
`quadlet::container::volume::Source::NamedVolume` after the
`compose_spec::Service` is converted into a `quadlet::Container` in
`cli::compose::service_try_into_quadlet_file()`.

Changed `cli::Unit::add_dependencies()` to `add_dependency()` which now
takes a dependency name `compose_spec::Identifier` and a
`compose_spec::service::Dependency` from `compose_spec::Service`'s
`depends_on` field. It also errors if the `Dependency` is not compatible
with quadlet.

Changed `cli::compose::networks_try_into_quadlet_files()` to use
`compose_spec::Networks` and added error docs.

Changed `cli::compose::volumes_try_into_quadlet_files()` to use
`compose_spec::Volumes` and added more docs.

Added docs to `cli::Container::name()`.

First, a `cli::GlobalArgs` is created by taking the `runtime` and
`storage_opt` fields from the `compose_spec::Service`.
Next, that is converted to a `quadlet::Globals` which is used in the
generated `quadlet::File`.

…ice`

Split up `compose_spec::Service` into separate parts in
`cli::container::compose`. Allows for destructuring, ensuring all fields
of `compose_spec::Service` are considered for conversion. Also, no more
`TryFrom<&mut ComposeService>`, yay!

`podlet compose --pod <POD>` is now `podlet compose --kube`.

The `name` field of a compose file is required when using `--kube`.
It is used as the name of the pod and in the filenames of the generated
`.kube` quadlet file and Kubernetes YAML file.

Frees `podlet compose --pod` for creating a `.pod` quadlet file from a
compose file in the future.
