Upgrade HolographDropERC721

[alexanderattar]

Describe Changes

• Adds HolographDropERC721V2
• Adds a new deployment script for it
• Adds the new contract to the registry
• Update the version to 2 (NOTE: The upgrade is incompatible from previous version therefore making it a MAJOR upgrade)
  • I thought about changing this to a uint32, but because it's a pure function the optimization would be minimal.
• Remove OpenSea operator filter registry because this royalty enforcement mechanism has been deprecated: https://opensea.io/blog/articles/creator-fees-update
  • Updates the deployment scripts to be compatible with the above
• Updates the price oracle proxy reference to the latest address 0xeA7f4C52cbD4CF1036CdCa8B16AcA11f5b09cF6E
• Moves the holographMintFee fee into the treasury (initially set to $1.00)
• Adds functions for getting and setting the mint fee
• Adds tests to check the new functions

To run tests:

1. run yarn ganache-x2 or yarn anvil
2. npx hardhat deploy --network localhost
3. forge test

Checklist before requesting a review

• I have performed a self-review of my code
• Code styles have been enforced
