Function create_block_template_with_outputs 

pub fn create_block_template_with_outputs(
    utxo_set: &HashMap<OutPoint, Arc<UTXO>, FxBuildHasher>,
    mempool_txs: &[Transaction],
    height: u64,
    prev_header: &BlockHeader,
    prev_headers: &[BlockHeader],

Same as create_block_template, then replace the coinbase and merkle root.
