Serialization input/output

Files here contain hex strings and binary data representing types used for regression testing.

• *_hex: consensus encoded types represented as hex strings
• *_ser: consensus encoded types represented as binary data
• *_bincode: types serialized with serde as bincode

We consensus deserialize, serde serialize, then check against the expected data to verify no serde regressions have been introduced.
