Add a new 'store' field to the product

[zmoog]

You need the store id when you export the data using the json or ndjson output formats, so you know the store the data is coming from.

Here's an example:

$ rfrb it iphones --format ndjson | head  -n 1 | jq                                               zmoog/add-store-to-product  ✱
