SomberNight 6584ae2ef8 transaction: add note serialize_preimage is not caching Sighash.SINGLE ...

Unlike a full bitcoin node, we rarely (if ever) validate the signatures of arbitrary transactions,
so I don't think these DOS issues can really be used against us.

btw what is not explained in either source link is that the lack of caching is much
more serious for taproot as bip-342 lifted the 10 kbyte max size for scriptPubKeys.
