Fixbug: Import bitly_api python 3.5

[elinaldosoft]

There is a bug of import in Python 3.5 to the following packages Connection, BitlyError and Error. The error has origin in moment of importing, I think better use path relative in this case.

if you need this package in python 3.5 or later, try: pip install git+https://github.com/bitly/bitly-api-python/@refs/pull/41/merge
