Re-add preset contracts

[martriay]

For ERC20 and ERC721 tokens mainly

Hey, I just finished a first Cairo 2 version of our ERC-3525 including presets (using unsafe_new_contract_state exclusively).
Feel free to benchmark it if needed for your contracts, I would be glad to help.

@bal7hazar thanks. I'm not sure I understand correctly, are you suggesting we include ERC-3525 into our library or are you suggesting comparing ERC-20 and ERC-721 performance against it?

@martriay hey, it was just to show how I wrote presets for ERC3525 in case you would like to benchmark them before you write ERC20 and ERC721 presets

@bal7hazar what you mean by benchmarking? performance or to simply compare?

@martriay more about the architecture and the design of the solution

Closing this issue as we decided to follow the steps of the Contracts for Solidity repo and leave only basic presets in the repo, and let Wizard for (coming soon for cairo 1+) to cover the rest.
