python/ftp - Hotfix FTPDataConnect.__init__ requiring defaults for args

ISSUE TYPE

• Bugfix

SUMMARY

Fixes #324. Adds dummy defaults to the FTPDataConnect constructor, as required by PR #318 (commit acc8bc87723181459081e525126368f30edecd81)

I was thinking about adding further sanity checks for the values, but then I checked the fix in the PR and it seems adequate to leave it like it is now.
