Problem: Attestation is failing for tokens that were created recently.
Cause: Metaplex has resized the SPL token metadata account from 679 bytes to 607 bytes in the commit (6b2e869) However, the token-bridge is still using the older version of the SPL token metadata and validating the size based on the older constant. As a result, this check fails to attest tokens that are using the new metadata accounts.
Solution: To resolve this, I have added an additional condition with the new metadata length constant, allowing the validation to pass if the SPL token has either of the two metadata account lengths.
