The tests I've written do not test the "blockTag" parameter for `getBalance`, `getStorageAt`, and `getTransactionCount`, and I'm having wondering what you think the best approach to that might be?

@holgerd77 I pared this down to as few lines of code as I could manage. hope this is closer to what you were looking for. :pray: the benchmark performance is...

Took a stab at this following the model of the Ultralight provider. Biggest question has to do with `getAccount` - and what the equivalent `ethers` call is.
