Question: getting all tokens by address about erc721a

@Vectorized Thanks! Perfect answer there, useful code and use cases.

The reason I added the Minted event is we're not actively listening to the contract, and it'd be far less events to collect than listening to Transfer.

Also, we'll further need to filter to filter Transfer events to those with a from address 0x0, since the event is also used to transferring between accounts, and burning.

See #115.

If you are listening to events to build up some kind of database, note that each NFT minted emits a Transfer event (with the from address as the zero address). So, emitting a Mint event is not necessary.
