EIP-747: Add wallet_watchAsset

I would be nice to have this functionality like Metamask. You can add a custom ERC20 token.

window.ethereum.request({
    method: "wallet_watchAsset",
    params: {
        type: "ERC20", // Initially only supports ERC20, but eventually more!
        options: {
            address: "0xc2768beF7a6BB57F0FfA169a9ED4017c09696FF1", // The address that the token is at.
            symbol: "PE", // A ticker symbol or shorthand, up to 5 chars.
            decimals: 6, // The number of decimals in the token
            image: "https://raw.githubusercontent.com/peronio-ar/branding/main/logo/256.png", // A string url of the token logo
        },
    }

@hboon @agustinkassis This is quite a good idea actually! A dapp can suggest tokens to add to your wallet (if you agree presumably).

I will also add it into my TokenScript Token factory so the wallet adds the token, if it doesn’t have a good token discovery (looking at you Metamask).
