pset_swap_tutorial fails getting addresses index 0 from output

[wintercooled]

Running

python contrib/assets_tutorial/pset_swap_tutorial.py

I get an error at line 215: address = out["scriptPubKey"]["addresses"][0] as out["scriptPubKey"] doesn't contain an array of addresses, just one address field.

The error output:

This was running Elements 0.22.0.2.

I can fix this by replacing:

out["scriptPubKey"]["addresses"][0]

with

out["scriptPubKey"]["address"]

which allows the example to complete, but I'm not sure if this obvious looking fix is missing some other subtleties.

A fix can be found here: master...wintercooled:elements:fix-pset-example

But it seems so simple a fix I might be missing something. If not I will create a PR.
