Flow Customisation: Override delivery details with a custom built component

Limio for Salesforce has a built in flow component for capturing delivery details.

Since the collected address is then passed to a flow variable, another custom component could be built, to replace this one.

When building a custom component, its output must be stored in a stringified json object that must have the following format

{
"CompanyName": "Limio",
"FirstName": "giacomo",
"LastName": "test",
"MailingCity": "London",
"MailingCountry": "GB",
"MailingPostalCode": "SE1 3ER",
"MailingState": "London",
"MailingStreet": "Leathermarket St, Weston St 12",
"MailingBuildingNumber = "12",
"MailingStreetName = "Weston St"
}

Note: MailingStreet maps to an address1 standard address field in Limio (it may combine street name and building number), while it's also possible to map streetName and building number as standalone fields to MailingStreetName and MailingBuldingNumber respectively.

Once all of the above information are being collected, the content needs to be stringified and its value assigned to the " address" flow variable.

This is then used in the rest of the flow and in turn sent to Limio as part of the order.
