detect account change in wallets that does not expose events (all non-nami wallets)

Right now it's hardcoded to nami, but we should probably use some feature detection instead

This is not hardcoded any more, but discovered using feature detection with walletApi.experimental.on(...). However, it's a shame that most wallet providers does not implement this. I am planning to add a CIP for this.

We could implement this now, with some long polling kind of thing, ie.

If the wallet does not support events for changing account or network, we could emulate this with a setTimeout that periodically checks if the account or network has been changed. I am not super excited by this for two reasons; 1. the UX won't be great, and 2. it's just a waste from a resource / performance point of view. I really like how use-cardano works now with regards to not doing anything when you're not interacting with your wallet or the blockchain.

I might give this a try, just to see how it plays out, as an intermediare solution until (and if) I can get a CIP to pass.
