Consensus Specs: Tim's Vision

v1.4.0-beta.0 -- Consensus Specs: Tim's Vision -- is the first beta release for the upcoming Deneb upgrade. The move from alpha to beta signifies that Deneb is considered to be feature complete and not intended to change substantively from here. That said, there may still be minor patches, configuration changes, bug fixes, and (unlikely, but possible) feature removals.

EIP 4788, 7044, and 7045 are added to the Deneb build in this release. It is expected that devnets will shift to being fully featured (rather than just 4844) in the coming weeks.
