Merge #566

566: Replace periodic sync with events r=holzeis a=holzeis

Replaces periodic syncs of ...

- wallet
- offers (Event::Offer)
- balance (Event::WalletInfo)
- history (Event::WalletInfo)
- channel state (Event::ChannelState)

The only sync that is still triggered from flutter is the sync of the cfd orders. It would be nice to have the stream available in the cfd module and only push a cfd if it has been opened or closed, instead of syncing in an interval, but that needs some more design.

Also introduces a `Ready` event notifying the flutter app that the ldk node has successfully started.
