Implement HyperNova's IVC into the FoldingScheme trait (#116)
- 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)
