• Onchain Runtime

Summary

• Integrated with the new storage model, making required objects Storable to allow storing MPT leafs as Sps.
• Added segment IDs to Zswap constructors. These should be set to 1 for fallible offers, and 0 for guaranteed offers.
• Renamed ZswapLocalStateNoKeys to ZswapLocalState, removing the existing (with keys) state.
• Switch from Pluto-Eris to BLS12-381.
• Switched to using data providers instead of direct prover keys and parameters.
• Add a data provider to fetch key material for Midnight. The source of this may be overridden with the MIDNIGHT_PARAM_SOURCE environment variable.
