📚 Description

Added additional method that allows for using bitbucket as a repository source using the bitbucket api for downloading repository as a zip/gz file (https://confluence.atlassian.com/bbkb/how-to-download-repositories-using-the-api-1188780893.html). As far as I know bitbucket only allows for downloading the entire branch or specifically uploaded files via a different API. These changes allow for downloading all the files of a specific branch.

Makes it easier to use bitbucket as a content collection source.
