Dev (#15)

* Added zk cryptography (#14)

* Add hash functions

* Add zk cryptography

* fix deps

* fix test runner

* linted and reorganised hash functions;
switched all files to one pragma circom version

* linted wasm-test

* updated hardhat-zkit package version

* linted zk cryptography circom files

* cleaned up wasm-test js files

* renamed functions to camel case

* removed double spaces;
added spaces between operators;
linting

* refactored comments, corrected typos

* linting

* updated dependencies

* rewrote tests from wasm to hardhat: bigInt folder

* rewrote tests from wasm to hardhat: bitify folder

* rewrote tests from wasm to hardhat: hasher folder

* rewrote tests from wasm to hardhat: int folder

* transfered common functions to helperFunctions file

* fixed typos:
ellipic -> elliptic
ADDERS_NUMBER -> ADDRES_NUMBER

* allowed UnlimitedContractSize for verifiers contracts

* updated hardhat-zkit version

* rewrote tests from wasm to hardhat: matrix folder

* fixed typos

* switched to same order of inputs in sig folder

* rewrote tests from wasm to hardhat: signature folder

* rewrote tests from wasm to hardhat: ec folder

* fixed typos

* trying to fix compile in ci

* trying to adjust ram in case its github limit

* refactored possibly undefined vars in tests

* checking a pipeline without 4 biggest circuits

* fixed tests for brainloop:
automatically generated verifier names were too long,
so corresponding contracts were not generated;
fixed by creating verifiers dirrectly whithin the tests

* refactored assertion checks in tests

* updated zkit hardhat version

* let -> const in tests

* deleted wasm-test folder

* trying to fix ci

* trying to fix ci command

* disabled ci checks

* consistency in tests

* added missing BigSubNonEqual test

* cleaned up

* mock directory renamed to main;
mock is for tests now

* moved mgf1.circom to utils

* fixed typo in Pippenger

* fixed paths (renamed mock to main)

* switched to local circuits instead of circomlib's

* renamed utils to mask

* CommitmentVerifier -> Commitment
SparseMerkleTreeVerifier -> SparseMerkleTree

* updated dependencies

* updated tests

* fixed package-lock

* linting

* removed unnecessary dependencies

* returned chai deps

 The library consists of circom circuits that extend the capabilities of [solarity/solidity-lib](https://github.com/dl-solarity/solidity-lib) to be used in magnificent ZK applications.
 
-- Versatile commitment / nullifier circuit.
-- Optimized Sparse Merkle Tree (SMT) data structure.
