`BundleManager.handlePastEvents` may exceed JSON RPC response size limit

[kaiix]

When a bundler is started and a bundle is sent for the first time (https://github.com/eth-infinitism/bundler/blob/v0.5.0/packages/bundler/src/modules/BundleManager.ts#L55), all past events of entrypoint are scanned (https://github.com/eth-infinitism/bundler/blob/v0.5.0/packages/bundler/src/modules/EventsManager.ts#L37). This may fail because the response from RPC server's eth_getLogs exceeds the size limit.

Part of the error logs:

  reason: 'processing response error',
  code: 'SERVER_ERROR',
  body: '{"jsonrpc":"2.0","id":55,"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, 0x2014fd1]"}}',
