Description

Various refactors for the aggregation:

• Updated error enums to include descriptive error messages.
• Renamed sp1_aggregator structs to use more explicit and descriptive names that better reflect their purpose and contents.
• Updated the hash implementation in the to use sp1 built-in hash_bytes function. This eliminates the conversion from u32 to u8. This required us to update the hash in the sp1_aggregator program to convert u32 to u8 in big endian instead of little endian. This change is especially useful for sdk users, as it abstracts away internal details of the vk hashing, which they have to provide when trying to verify proof inclusion in agg mode.
