Open HRMP channels between AssetHub and Unique Network

This proposal is to open HRMP channels in both directions between AssetHub (ParaID 1000) and Unique Network (ParaID 2037).

Integration between AssetHub and Unique Network (an NFT parachain) is an essential piece of Polkadot ecosystem interoperability. It will open the stability and promise of persistence of AssetHub to Unique Network projects, and abundance of NFT features and flexibility offered by Unique Network to the rest of the ecosystem. The integration will also make USDT, USDC, and other currencies available to Unique Network projects, which will eventually result in increased TVL of the ecosystem overall.
