Support DN404 tokens

[rkalis]

Some people created a new token standard. We'll need to research what that means for Revoke and whether we need to / can support these tokens.

Looking at these lists from coinmarketcap and coingecko, it looks like this token "standard" was mostly a fad and isn't going to gain a big market share. Taking a quick look at the token standard, it looks like the current version of Revoke.cash should handle these tokens as if they were ERC20 tokens. So we can close this issue as a wontfix.
