feat: archiver fork block num

[alexghr]

This PR adds a start point for the archiver so that it doesn't scan the whole L1 chain.

[spalladino]

TIL the default syntax for destructuring

[spalladino]

Hmm is it ok that no CI jobs at all were run...?

Hmm is it ok that no CI jobs at all were run...?

not ok. I think it's because my PR was draft before. I'll merge in master

Detailed results

All benchmarks are run on txs on the Benchmarking contract on the repository. Each tx consists of a batch call to create_note and increment_balance, which guarantees that each tx has a private call, a nested private call, a public call, and a nested public call, as well as an emitted private note, an unencrypted log, and public storage read and write.

This benchmark source data is available in JSON format on S3 here.
