P2MS redeem in compat SegWit transaction example

This is the similar to transaction showcased in tx/multisig_redeem.pl example, but it uses P2SH(P2WSH) output instead of native P2WSH. In addition, it introduces a second P2WPKH input.

This code was used to produce testnet transaction: https://mempool.space/testnet/tx/f5ee861935e8b675f25c8f976ad747478c8185d06cb632d79550d9c58c0350a2
