Update the Authorizing Data Commitment for the ``sighashInfo`` changes to the tx format.

[arya2]

It is not specified how SighashInfo is incorporated into the digests.
I think we only need to update auth_digest and specifically:

• transparent_scripts_digest
• spend_auth_sigs (A.2b) in sapling_auth_digest
• binding_sig (A.2d) in sapling_auth_digest
• bindingSigOrchard (A.3b) in orchard_auth_digest
• spendAuthSigsOrchard (A.3a.ii) in orchard_auth_digest
• issueAuthSig (A.4a) in issuance_auth_digest

For each of these signatures, the signature should be replaced by (SighashInfo || signature) where SighashInfo = sighash_version || associated_data.

Should be fixed by #1077

#1077 merged so I don't know why this didn't auto-close.
