Providers could do better to handle errors from the Infura and Alchemy API.

Describe the Problem

Default provider with Etherscan, Alchemy, Infura and Pocket. Querying a contract's logs over entire blockchain. Etherscan does well because it just returns 1000 so I can just start calling from blockNumber + 1 of latest event. However, Infura:

{
  "jsonrpc": "2.0",
  "id": 47,
  "error": {
    "code": -32005,
    "data": { "from": "0xBDE5F8", "limit": 10000, "to": "0x102DBCC" },
    "message": "query returned more than 10000 results. Try with this block range [0xBDE5F8, 0x102DBCC]."
  }
}

After parsing response that was emitted in 'debug' event. And, Alchemy:

{"jsonrpc":"2.0","id":43,"error":{"code":-32602,"message":"Log response size exceeded. You can make eth_getLogs requests with up to a 2K block range and no limit on the response size, or you can request any block range with a cap of 10K logs in the response. Based on your parameters and the response size limit, this block range should work: [0x0, 0xd043b8]"}}

I have tried to just add handling for this on my own in the BaseProvider object but I can't even seem to get a simple console.log() to work. Something to do with typescript compiling or whatever. Also, I think the Pocket provider request failing does not even emit a 'error' nor a 'debug' event and just causes the entire program to hang.

It is a pity that this is not handled because the Infura API would return a whole 10k events if the correct block range was used. They even give you a block range in their response error body. Just some simple parsing would extract the block range and then a retry of the getLogs call with the new range, instead of just emitting a debug event, would bring a phenomenal transformation of how these two providers integrate into this amazing library.
