WIP: Add Community Token Implementation

[defijesus]

WIP - please don't merge & roasting is encouraged

This PR adds a new Token implementation that make the following modifications:

• Adds bytes32 merkleRoot, uint256 auctionOffset , bool isClaimOpen & mapping(uint256 => bool) claimed to Storage.
• Adds onlyOwner functions to modify merkleRoot, auctionOffset & isClaimOpen.
• Adds 2 public payable claim functions that verify merkle proof and mint respective token to respective recipient
• Adds public rescueEth function to send all Token ETH balance to Treasury
• Modifies mint function to use auctionOffset

This results in an existing NFT community to create a snapshot of holders, create a merkle tree with holders list, each community member can now claim a their corresponding token and enjoy all the nouns-builder ecosystem goodies.

The test suit contains full coverage of modifications + upgradeability.

TODO:

• - Allow multiple NFT claims in single function call
