sherlock Having a . at the end of a username causes an error

Installation method

PyPI (via pip)

Description

When trying out a username that ends in ., there is an error with the way the program looks for the username. Currently, for the site exposure it goes to {username}.exposure.co, but in the event the username provided has a ., it will error as you can't have 2 dots in a URL. The error trace I get is this:
