SFTP x Excel cannot be tapped

[ElmoreV]

The tap as is, cannot correctly extract an Excel file from an SFTP server when connecting using a password.

I have found three issues in connecting to SFTP and tap an excel file, where two are fixed by PR #86 and the third is using a password in the uri as sftp://name:password@host:port//path/to/

At first connecting to the SFTP server and finding the file works as intended. The consequent streamreader then forgets that this is the intended route. A patch that works for me would be to add this in file format_hanlder.py in get_streamreader(uri,...):

def get_streamreader(uri, universal_newlines=True, newline='', open_mode='r', encoding='utf-8'):
    kwarg_dispatch = {
        "azure": lambda: {
            "transport_params": {
                "client": BlobServiceClient.from_connection_string(
                    os.environ['AZURE_STORAGE_CONNECTION_STRING'],
                )
            }
        },
        "sftp": lambda: {
            "transport_params": {
                   'connect_kwargs':{'look_for_keys':False}

            }
        }
    }

but this seems to prevent a correct handling whenever keys are actually present and look_for_keys needs to be True.

Note: it might be due to keyfiles already existing in the /.ssh/ folder, and failing before the authentication using the password is never correctly checked.
