chore: Replace old POC for Neptune with the real deal (#848)

The Neptune package that was provided so far was the result of a proof-of-concept that was made
before the eventual Neptune API was made available. Replacing this with the generated L1 for
Neptune, that would otherwise not have been available at all.

Fixes #807
