Add an interval parameter to JsonRpcBatchProvider

[pugbyte]

Describe the Feature

Currently the interval for batching requests in JsonRpcBatchProvider is hard-coded to 10ms. It would be helpful if this was configurable, as I've found that the 10ms window isn't lenient enough for some cases. I imagine this could be an option on the constructor of JsonRpcBatchProvider.

This is already in v6 and I am trying to keep v5 changes to a minimum. :)
