Package import fails if fastfuels key not set as an envrionment variable

[wxcutch]

I just installed the sdk in a fresh conda environment. When I run from fastfuels_sdk import api I get the following error:

     31 if not api_key:

     34         "Please set this variable with your API key."
     35     )
     36 config = {
     37     "header_name": "api-key",
     38     "header_value": api_key,
     39 }
     41 _client = ApiClient(**config)

RuntimeError: FASTFUELS_API_KEY environment variable not set. Please set this variable with your API key.

In case someone else is having the same issue and also doesn't want to globally set the environment variable, I put this in the code block before the import to fix it:

import os
os.environ['FASTFUELS_API_KEY'] = 'your-key-here'

Thanks @wxcutch. This is related to #98. The way I read the code this shouldn't be happening, but clearly I'm wrong and this needs to be looked into.
