[Bug]: `marketplace.getAllListings()` is cripplingly slow.

Prerequisites

• I have checked that @thirdweb-dev/sdk is on the latest stable version and the bug still exists.
• I have checked existing issues and I was unable to find a duplicate of this.

Optional

• I am willing to contribute a PR that fixes the problem with some guidance.

Describe the bug
I have a marketplace contract created with ThirdWeb. I have 2 direct listings on my marketplace. When i retrieve listings from the marketplace with the ThirdWeb SDK, it takes up to 10 seconds, even when using Alchemy provider. This results in page loads up to 10 seconds, which is simply unacceptable from an end-users perspective.

Expected behavior
Getting marketplace listings should be a fast operation, so that user's don't need to wait ages for listings to load.

Screenshots

Hey @skoshx ! Sorry for the late reply on this. There's a few things that we fetch for each listing: the info from the marketplace contract, the info from the listed NFT (including the metadata from ipfs) and the info from the ERC20 currency if any. All of that happens in parallel so it should be pretty decent performance.

One thing we could do is provide a minimal getAll call that only retrieves the raw information from the marketplace contract, and let the user fetch additional information lazily. Would that help in your case?

@joaquim-verges Hello, sorry for my cripplingly slow answer, I have been really busy! Anyways, yeah I think either another function that only gets raw information like you mentioned or add an option of something like includeMetadata to the filter object of marketplace.getAllListings().
