Loading NFTs in bulk with JSON files

[sbermingham93]

Hello, and firstly thank you for a great library!

We are aiming to load NFTs in bulk including the JSON files.

The current implementation is as follows;

1. use metaplex.nfts().findAllByMintList({ mints: [p1, p2,....] })
2. For each meta returned call the metaplex.nfts().load({metadata}).

I'm hoping there is a better option as it requires many requests.

Thanks!
