Medalla data challenge addendum

One of the biggest requests we've gotten regarding the Medalla Data Challenge is for tips on how to access data to analyze. With that in mind, we're extending the submission scope to include tooling for building public datasets.

Submissions must:

open source the tooling you use and make it easy to use
put your data somewhere that's publicly available, like Google BigQuery

Here are some tools to get started:

wealdtech/chaind for pulling historical state at a given node
lighthouse crawler for pulling live attestation gossip seen by a lighthouse node
- clone the repo and run cargo run --release --bin crawler
