This commit adds the config flag
parseAEADEncryptedV4KeysAsLegacy.When reading private keys which were encrypted by OpenPGP.js v5 (or older) using
config.aeadProtect = trueandconfig.v5Keys = false, this option must be set, otherwise key parsing and/or key decryption will fail.OpenPGP.js up to v5 used to support encrypting v4 keys using AEAD as specified by draft RFC4880bis (https://www.ietf.org/archive/id/draft-ietf-openpgp-rfc4880bis-10.html#section-5.5.3-3.5).
The config option to do so was not initially marked as "experimental", so there is a risk that some apps have been using it in production.
This legacy format is incompatible, but fundamentally indistinguishable, from that of the crypto-refresh for v4 keys, merged in #1630 . If a key is parsed based on the wrong format, the parsing may still succeed, but key decryption will always fail.
Thus, we rely on the caller to instruct us to process the key as legacy, via the new config flag.
