/*
Complete the function getShippingAddressLines so that it returns
an array of strings that represent the shipping address.
The format of lines should be:
<first_name> <last_name>
<company>
<address_1>
<address_2>
<city>, <province> <postal_code>
<country_code>
<phone>
Any empty line (e.g. if <company> is empty or missing) shouldn't be included in the final array.
An example of the resulting array:
[
  'Arno Willms',
  'Acme',
  '14433 Kemmer Court',
  'Suite 369',
  'New York, NY 10001',
  'US',
  '1-212-555-1234',
]
