Function extract_p2sh_redeemed_script 

pub(super) fn extract_p2sh_redeemed_script(
    unlock_script: &Script,
) -> Option<Vec<u8>>

Extract the redeemed script bytes from a P2SH scriptSig.

The redeemed script is the last data push in the scriptSig. Returns None if the scriptSig has no push operations.

Precondition

The scriptSig should be push-only (enforced by mempool_standard_input_scripts before this function is reached). Non-push opcodes are silently ignored.
