feat(serialization): Add Serde support for `semi_avid::Block` struct

This PR adds serialization and deserialization support for the semi_avid::Block struct using Serde, while maintaining compatibility with Arkworks' canonical serialization.

This implementation enables compatibility with ecosystem dependencies like libp2p that rely on Serde for network serialization and data exchange when using predefined codecs (like bincode, CBOR or JSON), improving interoperability of our cryptographic primitives across different libraries and network protocols.

Changes:

• Implement Serialize and Deserialize traits for semi_avid::Block
• Use Arkworks' canonical serialization with compression
• Use a Visitor to serialize and deserialize the bytes returned by ark_serialize
• Add Bincode as dev dependency for testing
• Add test for serialization round-trip validation using semi_avid::Blocks, array of semi_avid::Blocks and encapsulated semi_avid::Blocks into enums.

Implementation Details:

• Serialization converts the block to a byte vector using the CanonicalSerialize trait
• Deserialization reconstructs the block from bytes using the CanonicalDeserialize trait

Added a test that:

• Generates and prove some blocks
• Serializes blocks using Bincode
• Deserializes and compares blocks
• Ensures correct serialization and deserialization integrity by comparing each deserialized objects to the original objects.
