x: grc721 full refactor

[leohhhn]

Description

This is a refactor of the GRC721 package. The idea with this is that we want a fully "by-spec" implementation, and then we can build upon it and experiment.

The process of writing is done in Go, and later converted to Gno.

Can you assign me some issues to solve together ?

wdyt about using []byte as tokenId type?
It would be a superset of eth's uint256 while allowing tokens to have more self-describing and expressive keys
I guess it would be annoying to bridge gno nfts to ethereum on the other hand

Hey @linhpn99 @n0izn0iz,

I've finished the implementation for this and added an example usage realm. If you want, you can take a look and tell me what you think.

Will move this code to the monorepo for visibility :)

is it safe that you call panic() when handling the exception ?
