As a motoko dev, I want to use the dip721 standard so that i can deploy nft canisters using motoko

Is your feature request related to a problem? Please describe. There is a Rust codebase for this, but no Motoko codebase. Motoko is the official language of the IC and more user friendly then Rust. The same example should be available for motoko as well. https://github.com/dfinity/examples/tree/master/motoko/dip-721-nft-container

Describe the solution you'd like Clone the Rust DIP721 example over to motoko.

Describe alternatives you've considered
