[EPIC] ERC Registry

[Nana-EC]

Problem

On Hedera both HTS tokens and ERC tokens are supported. However, HTS tokens have improved APIs and allow for easy retrieval of existence and balance across accounts on the network.
Like other EVM chains, it is not easy to know what all ERC tokens are specified within smart contracts on the network without first knowing the contracts and confirming they accurately implement the interface needed.
With this in mind it's difficult for the mirror node explorer or other apps to know and display ERCs

Solution

Implement a new project to create a registry of contracts that are highly likely to be ERCs. The Mirror node explorer and other applications can use this list as a foundation to enhance their user experience.

@quiet-node and @natanasow to sync up on this and produce a design doc first highlight approach.
Doc should be placed in tools/erc-repository-indexer/docs/registry_design.md

Suggestion from @acuarica to utilize the verification service to add additional confidence.
This could be done using the verification service APIs
