Bridging NFTs across layers

Intro

NFTs built on L2 can't be bridged to L1, which creates NFT silos. This document creates a way to easily transfer NFTs across layers and reduce the gas requirements by minting the NFTs on Layer 2. This lets the user decide when they would like to withdraw their NFTs to Layer 1.

How it works

The Owner will provision the L1_NFT_Collection with the deployed L2_NFT_Collection, specifying:

Address of the L2_NFT_Collection
Chain ID of the L2_NFT_Collection
Location of the NFT, mapping of the Chain ID by the NFT ID
Range of Allocated NFTs, e.g. #1-100, 60-61, etc.
