Trie: Batching multiple leaf proofs

[s1na]

When proof for multiple leaves of the trie are required simultaneously, batching the proofs together as proposed here can reduce the total overhead. A new method can be added, e.g. proveBatch or proveMultiple that accepts an array of keys and returns the batched proof. This can potentially be useful in stateless and light clients.

So this essentially means that we can now create the proof to feed in verifyRangeProof, right? Very exciting.

The above comment is hard to read, this here is an issue, what do you mean with "this" from "so this essentially..."? 🤔

[jochem-brouwer]

Yeah I actually meant the issue itself :)

I will actually close here before it gets forgotten again, this should - latest - be implemented with the completion of #2821 I guess (let me know if I am wrong here).
