## Proposed Changes Implement the consensus changes necessary for the upcoming Altair hard fork. ## Additional Info This is quite a heavy refactor, with pivotal types like the `BeaconState` and `BeaconBlock` changing from structs to enums. This ripples through the whole codebase with field accesses changing to methods, e.g. `state.slot` => `state.slot()`. Co-authored-by: realbigsean <seananderson33@gmail.com>
