* change: CircomWrapper constructor to use raw bytes

* chore: tmp update to latest circom-compat

* feat: Introduce PathOrBin to support in-browser CircomWrapper usage

This changes the associated type `Params` of the `CircomFCircuit` to use
the newly created `PathOrBin` type.

This allows the user of the lib to directly send the binary of the files
already read or instead, provide a path to it and let `sonobe` do the
work.

With this, Circom should be already usable from the browser if we allow
JS to take care of reading the `.wasm` and `.r1cs` files.

* feat: Introduce PathOrBin to support in-browser NoirFCircuit usage

This commit temporarilly stands on top of
https://github.com/dmpierre/arkworks_backend/pull/1 referenced as `rev`.

This changes the associated type `Params` of the `CircomFCircuit` to use
the newly created `PathOrBin` type.

This allows the user of the lib to directly send the binary of the files
already read or instead, provide a path to it and let `sonobe` do the
work.

With this, Noir should be already usable from the browser if we allow
JS to take care of reading the `circuit.json` files

* chore: Update deps to branch instead of `rev`

* fix: use PathOrBin in examples

* fix: clippy

* fix: read file length for initializing vec size

* feat: enable hiding commitments in nova and hypernova

* fix: set blinding values for witness vector

* fix: remove cloning of the cyclefold running instance

* fix: do not re-use blinding values between prove steps

* fix: specify whether the witness should use blinding values using a
const generic

* feat: create a `dummy` method for nova witnesses as well

* chore: clippy - removed unused imports

- 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)

* refactor test of compute_c circuit to use multiple lcccs&cccs instances

* refactor hypernova's compute_c circuit to reduce from `110635` to `553` constraints

* fix: change circom fcircuit to extract indexes of inputs and add keccak satisfaction test

* fix: disable wire mapping when loading r1cs

* chore: update .gitignore and compile.sh

* fix: use fixed circom-compat branch

* fix: use slice rather than vec ref

* chore: add keccak-chain circom

* chore: trigger checks

* fix: make typos check circom files names but not their content

* chore: remove keccak, add tests with more lightweight circom templates, test that circom circuits correctly result in Ok and Err when needed

* chore: trigger checks

* fix: re-add circuit for full flow example, change naming

* chore: comment with link to issue 104, disable constraints check

* chore: remove `full_flow_example` from the examples and its
corresponding circom circuit

* chore: update `circom-compat` repo

* chore: clippy

* chore: stop excluding circom files from typos checker

* chore: remove changes on `typos.toml`

* 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
