Expand scope of this repository

[mfornet]

I propose to include in this repository not only native Ethereum tokens bridged, but every other legit token native on NEAR and deployed in Aurora, as well as native Aurora Tokens, native BSC token bridged, and new tokens coming from other bridges.

Motivation

All this are tokens relevant for Aurora network.

This will allow creating an official Aurora tokenlist (see #19) endorsed by Aurora Labs, that can be imported in several applications, like Metamask, AMM, etc...

Goal

Define an extended format that allow specify more details about the tokens being added.

• native network
• aurora_address should be mandatory field

Change repository name to aurora-assets
