To configure stream processors for containerd, entries in the config file need to be made.
The `stream_processors` field is an array so that users can chain together multiple processors
The `stream_processors` field is a map so that users can chain together multiple processors
to mutate content streams.
Processor Fields:
* `id` - ID of the processor, used for passing a specific payload to the processor.
* Key - ID of the processor, used for passing a specific payload to the processor.
* `accepts` - Accepted media-types for the processor that it can handle.
* `returns` - The media-type that the processor returns.
* `path` - Path to the processor binary.
* `args` - Arguments passed to the processor binary.
```toml

id = "io.containerd.processor.v1.pigz"
[stream_processors]
[stream_processors."io.containerd.processor.v1.pigz"]
accepts = ["application/vnd.docker.image.rootfs.diff.tar.gzip"]
returns = "application/vnd.oci.image.layer.v1.tar"
