Event Sidecar filter for empty blocks

As the dev team, let's create a sidecar filter to get empty block data so that the Association can consume this for their ESG Dashboard with Proof.io, and so the internal KPI Dashboard can consume this for reporting on empty blocks and demand.

Considerations:

• Unless there's a better way to do this, I assume the calculations like percentage of empty blocks since date/block height would best be done on the dapp side of the equation.
• Calculating the usage percentage per block could also be explored.

@hoffmannjan @zajko Confirming - this would not be done in sidecar but in block explorer middleware, correct? If so, I will move it to the correct repo.
