Library fails to construct correct request URLs on Windows.

[colleen-love]

When making a request on a windows machine, the URL of the request is formatted incorrectly. Here's the request for GET user:

-----------REQUEST-----------
GET https://uat-api.paylution.com/rest/v3/users%5Cusr-00000000-0000-0000-0000-000000000000
User-Agent: Hyperwallet Python SDK v1.3.0
Accept: application/json
Content-Type: application/json
Authorization: Basic {auth}

The request should look like this:

-----------REQUEST-----------
GET https://uat-api.paylution.com/rest/v3/users/usr-00000000-0000-0000-0000-000000000000
User-Agent: Hyperwallet Python SDK v1.3.0
Accept: application/json
Content-Type: application/json
Authorization: Basic {auth}

The culprit is line 117 of api.py

response = self.apiClient.doGet(
    os.path.join('users', userToken)
)

It should look like:

response = self.apiClient.doGet('users/' + userToken)

I would make a PR but this bug happens 54 times and is a part of most requests.
