204 ERC721 - Edit Mint Windows, Allowlist Mapping

1. Modify / Edit mint windows

Edit Mint Windows

// Modify the mint windows
   function editMintWindows(
      bool _publicMintOpen,
      bool _allowListMintOpen
  ) external onlyOwner {
      publicMintOpen = _publicMintOpen;
      allowListMintOpen = _allowListMintOpen;
  }

2. Set allowlist mapping to save allowlist addresses

• only hardcore people, certain people can mint this NFT
• set the allowlist, remember to add [""]

set allowlist

• create array for mapping
• create a for loop

set allowlist

balance = 0.001 ETH

3. Clean up code

• internalMint
