feat: Add CLI command for gathering proving metrics (#8221)

Run `yarn aztec prover-stats --l1-rpc-url
https://provernet-mainnet-fork.aztec.network:8545/$APIKEY -c 677692
--start-block 15918000 --batch-size 200 --node-url
https://api.aztec.network/provernet/aztec-node-1/$APIKEY` to get prover
stats from provernet.
