Pwdsphinx

this release fixes:

- a more friendly error message if no configuration is found, yet allows to continue with defaults, so that eventual tests and programmatic use is possible.
- client actually uses the configured timeouts for network connections
- unittests are run in randomized order to detect flaky CI/CD infra
- unittests have 3s sleep between to accommodate for overloaded CI/CD infra failing tests because of resource starvation
- github codeql action is now enabled

forgot to adapt healthcheck op to the fix of the previous release.

This release fixes the abort when one or more threshold servers are not responding.
Furthermore it removes the exception output from the client, which can be enabled again by setting `debug=true` in the client config.
additionally the radicle repository has a new rid, this was noted in the readme.

this release comes with minor cosmetic and documentation fixes, and new:

- support for ssh-ed25519 keys.
- converters are documented properly

three important fixes:

- the reference server does not crash if not a proper ssl connection is made
- generating a minisign key might get stuck in an infinite loop during a create op.
- change ops also ensure all char classes are enforced, and converters expectations are satisfied.

This release most importantly fixes the case when someone checks out a pristine clone of the git repo and tries to run the unittests, they were failing. not anymore.

Furthermore:

- contrib/sphage has been replaced by pwdsphinx/converters/sphage providing a bit more flexibility and ux.
- a new contrib tool has been added pipe2tmpfile which allows commands that expect input from files to work with tools that pipe input.
- a new experimental minisign converter - you can now store your minisign private keys in sphinx.
