Fix bug with trailing 0 in CIK

[jadchaar]

In the orchestrator, I am using strip("0") to clean the CIK and format the URL for archive download. Filings for CIKs ending with 0 fail to download due to this issue since I am malforming a correct CIK. The fix is to change the orchestrator to clean the CIK using lstrip("0").

In addition to a regression unit test, I also validated that the code snippet below does not work on v5.0 but works after this patch:

from sec_edgar_downloader import Downloader

downloader = Downloader("Jad Chaar", "jad.chaar@gmail.com")

downloaded = downloader.get("424B2", "0000312070", limit=1)
print(downloaded)

Closes: #126
