Find or add tooling to allow for easier on chain analysis

[piersy]

Description

When investigating incidents it would be very useful to have a tool that would allow you to easily query data from the chain.

For example

• Show the round/gas used/mingas price/transactions for a block or range of blocks.
• Count the number of transactions in a block, grouped by sender address.

The graphql api from blockscout is very limited, we should investigate the graphql api in fullnodes and see what it can provide for us. If that turns up nothing, can we find other tooling that can help, or maybe we can write our own.
