* Add RecursiveCircuit
The RecursiveCircuit verifies N proofs of itself (N=arity), together with
the logic defined at the InnerCircuit (in our case, used for the
MainPodCircuit logic).
The arity defines the maximum amount of proofs of itself that the
RecursiveCircuit verifies. When arity>1, using the RecursiveCircuit has the
shape of a tree of the same arity.

* add different inner-circuits in the test, reusing the same verifier_data; polish recursion interfaces
* add InnerCircuit::Params
* rm non_base_node
* WIP refactor RecursiveCircuit
* wip. change approach on verifier_data of circuits used in recursivecircuit. arity=1 works
* recursion works fine without registering verifierdatas as publicinputs
* add hashing of verifier_data (out & in-circuit) methods with test
* connect previous and current verifier_datas hashes
* polish
* add InnerCircuit's public_inputs to the RecursiveCircuit
* extend recursive test
* polish & review suggestions
* unify fe/be NativeOp and NativePred
* remove Origin in favour of PodId
* Combine string and hash in Key
* use middleware::AnchoredKey in frontend
* merge frontend/middleware types
* refactor custom predicates
* clean up a bit
* fix middleware custom tests
* clean up
* clean up 2
* add acronyms in typos list
* Contains should take three arguments (root, key, value)
* Add a test for frontend Dictionaries
* Separate frontend and middleware operations
* Make tests pass: add arg to contains
* Cargo fmt
* Merkleproof verify circuit (#143)
* merkletree: add keypath circuit
* merkletree-circuit: implement proof of existence verification in-circuit
* parametrize max_depth at the tree circuit
* Constrain selectors in-circuit
* implement merketree nonexistence proof circuit, and add edgecase tests
* add non-existence proofs documentation in the mdbook, mv EMPTY->EMPTY_VALUE & NULL->EMPTY_HASH, dependency clean and public exposure methods
* review comments, some extra polishing and add a test that expects wrong proofs to fail
* Add circuit to check only merkleproofs-of-existence
With this, the merkletree_circuit module offers two different circuits:
- `MerkleProofCircuit`: allows to verify both proofs of existence and proofs
non-existence with the same circuit.
- `MerkleProofExistenceCircuit`: allows to verify proofs of existence only.
In this way, if only proofs of existence are needed,
`MerkleProofExistenceCircuit` should be used, which requires less amount
of constraints than `MerkleProofCircuit`.

Extend merkletree spec, init SignedPod section, add typos checker in CI
- extend merkletree spec, converting old hand-drawn diagrams to drawio
diagrams, and adding new diagrams (related: #6)
- init SignedPod section (related: #2)
- initial draft of the types dictionary, set, array (related: #26)
- add typos checker in CI (and correct the ones that were detected)
Note on drawio diagrams: each image file contains the metadata to edit the diagram in the draw.io website.
