Add Unstoppable Domains support (.crypto and new ones)

[mexcool]

What?

Add support for Unstoppable Domains by adding the events from the Registry contracts. The initial set up was only for .crypto TLD and then they made it for many more. I split into Crypto Name System (CNS) and Unstoppable Name System (UNS).

How?

I used abi-parser to build the table definitions. The new Registry contract for UNS is a proxy contract with the implementation being this.

All contracts are here.

I added all of them under one parent folder/dataset unstoppable_domains and kept same table_name as the contract name. I added a description to the CNS Registry to clarify those are for CNS.

Anything Else?

1. The contract_address must be the proxy right? even if I used the implementation in the parser.

@mexcool , I would restructure this slightly so all the files are within the folder unstopabbledomains or similar based on the entity.

Then you can split between uns/cns based on file names. CnsRegistry and UnsRegistry.
