 The `PayloadCodec` needs to implement `encode()` and `decode()` functions at a minimum.
 These should loop through all of a Workflow's payloads, perform all of your necessary marshaling, compression, or encryption steps in order, and set an `"encoding"` metadata field.

 This example verifies that an encoded payload matches the `binary/snappy` filetype -- i.e., that it was encoded using the same custom `encode()` function -- and if so, performs decompression followed by unmarshaling.
