Reverse ENS resolution calls should be batched, if multicall specified in the client

[apoorvlathey]

I had a long list of addresses that I wanted to display as ens names, but the publicClient.getEnsName() calls aren't getting batched right now, leading to getting rate-limited by the RPC even though the client has batch specified with wait as high as 1 sec.

Can you provide a minimal reproduction?

Here I have a simple React App for fetching ENS for 10 addresses: https://codesandbox.io/s/objective-thompson-jzxfc7?file=/src/App.js
I would expect the RPC calls to be batched and go via multicall, but on reviewing the networks tab, I see 10 individual RPC requests being made for each of these calls.

Hey @apoorvlathey
there's a solution with https://github.com/ensdomains/ensjs-v3/

but yes i'd love to see this also in viem, i dont want to have to install another library just for ENS name lookup
