Fetch repos doesn't support organisations

[OverkillGuy]

Say I want to get all my Github Org's repos info, for data analysis. Not just the public repos, but also the private/internal repos.

The endpoints are different for organisation, and this tool doesn't take it into account:

github-to-sqlite/github_to_sqlite/utils.py

Line 453 in ace13ec

url = "https://api.github.com/users/{}/repos".format(username)

github-to-sqlite/github_to_sqlite/utils.py

Line 455 in ace13ec

url = "https://api.github.com/user/repos"

The endpoints for organisation repos is instead (source):
url = "https://api.github.com/orgs/{}/repos".format(username)

Let's add support for organisations repo scraping.
