For publish, reduce tx # to 1

[alexcos20]

Now, the publish flow has two transactions:

• create nft + erc20 + price schema
• setMetaData

Why is that? because in DDO you need both nftAddress and datatoken address. So you need the 1st tx to be confirmed to get them

Can it be reduced ? Yes. We can pre-determine the nftAdddress & datatoken address, use those values to create the ddo and then have a helper function that bundles both in one tx
