* @dev ERC721DynamicIds is a clever trick to make trading NFTs with dynamic traits safe.
*
* Stable value represented by an NFT is a prerequisite for safe trading today.
*
* If the value of an NFT can be changed by the seller, they can rug the buyer by using up the NFT before they accept they buy offer.
*
* Dynamic ids solve that problem by burning the old NFT and minting a new one every time the value of an NFT changes.
* That invalidates all offers made for an NFT before the value changed.
*
* A naive implementation would perform literal burn and mint every time but that’s extremely gas-inefficient.
*
* A clever implementation changes NFT id every time its value changes, emits Transfer events as if the NFT was
* burned and minted, while in reality no storage writes are performed.
*
* For this to work, we use 32-byte numbers as ids where:
* - the first 16 bytes are calculated during the mint and never change again.
* - the last 16 bytes are calculated every time the value changes.
*
* This results in a new id being issued every time the value changes while keeping some unique part of it (the first 16 bytes)
* constant so that we can keep track of owners, allowances, and other properties.
*
* An id emitted in Transfer events and visible to the outside world is called a publicId.
* An id used internally to keep track of things is called a mintId.
*
* The last 16 bytes of mintId MUST equal zero.
*
* A watchful reader will notice that by splitting ids in two 16-bytes long parts, we increase the risk of id collision.

* That makes a collision unlikely for most protocols using this technique.
*
* Note that _safeMint function prevents minting NFTs with an id that already exists.
*
* To prevent DOS due to id collision, it’s advised protocols mix in block.timestamp into the mintId payload.

* Note: this contract requires a patch on OpenZeppelin ERC721 implementation such that the _update function does not emit
* the Transfer event because it only has access to a mintId while Transfer events should be emitted using publicId.
