Merge #20595: Improve heuristic hex transaction decoding
0f949cde3dff15170db7930b0f7345ff995c267d Add regression test for incorrect decoding (Pieter Wuille)
39c42c442044aef611d03ee7053d2dd6df63deb7 Improve heuristic hex transaction decoding (Pieter Wuille)
Pull request description:
The current hex tx decoding logic will refuse to decode valid extended-encoded transactions if the result fails the heuristic sanity check, even when the legacy-encoding fails. Fix this.
Fixes #20579
