Paramiko 4.0.0 breaks sftpretty init

[SebGay]

Hi,

First off, thank you for a great library! I'm creating an issue instead of a PR since I have no idea of the project standards/goals/directions.

paramiko 4.0.0 was just released, and has dropped support from DSA/DSS keys.

This breaks sftpretty's init [1] (can also see dss references 2, 3).

This could be hotfixed by modifying pyproject dependency line to 'paramiko>=2.7.0,<4.0.0'.

Removal of DSS support from future versions seems the only way to keep using the latest versions of paramiko.

Thank you!

Thanks for the heads up @SebGay. I'll get a PR out when I wake up, while I'm happy to see DSS go, deprecations are always a balancing act. This one seems fairly straighforward though.

PR is ready to go just waiting on a Github Actions issue where the ci process is hanging at the last step and not moving forward. One way or another this will be resolved today, sorry for the delay.
