- Adds the logic to support multi-instances folding in HyperNova's
AugmentedFCircuit & IVC.
- Adds also methods to generate new LCCCS & CCCS instances that don't
depend on the main folding chain, to be folded in in the next step
- Updates CycleFold circuit & methods to work other folding schemes than
Nova, adapting it to fold multiple points per circuit (instead of
2-to-1 as till now)
- Handle multi-instances folding in the FoldingScheme trait
interface, which expects 'None' in Nova, and 'Some' in HyperNova &
other multi-folding schemes.
- implement hash of public params for Nova & HyperNova
- abstract pp_hash computation for folding schemes
- add pp_hash to solidity contract generator to verify the decider proof
- implement the IVC `FoldingScheme` trait for HyperNova
- refactor Nova's preprocess logic to make it simplier to use
- add to Decider trait (& Nova's DeciderEth) a preprocess method
- get rid of the `init_nova_ivc_params` and `init_ivc_and_decider_params` methods in `examples` since this is achieved with the `FS::preprocess` & `Decider::preprocess` methods
- (update the examples code to the simplified interface using
FS::preprocess & Decider::preprocess)
* circom: add external_inputs
* adapt new external_inputs interface to the FoldingScheme trait and Nova impl
* adapt examples to new FCircuit external_inputs interface
* add state_len & external_inputs_len params to CircomFCircuit
* add examples/circom_full_flow.rs
* merge the params initializer functions, clippy
* circom: move r1cs reading to FCircuit::new instead of each step
* CI/examples: add circom so it can run the circom_full_flow example
