superstruct the AttesterSlashing (#5636)
* `superstruct` Attester Fork Variants * Push a little further * Deal with Encode / Decode of AttesterSlashing * not so sure about this.. * Stop Encode/Decode Bounds from Propagating Out * Tons of Changes.. * More Conversions to AttestationRef * Add AsReference trait (#15) * Add AsReference trait * Fix some snafus * Got it Compiling! :D * Got Tests Building * Get beacon chain tests compiling --------- Co-authored-by: Michael Sproul <[email protected]>
