Thank you for your commit, but I am encountering an issue when using thesshClient.executeCommand method.
When a command fails (i.e., returns a non-zero exit code), I cannot capture the stdin or stderr output.
Am I using the wrong method?

do {
    let buf = try await client.executeCommand(command)
    let result = String(buffer: buf)
    return result
} catch let error as SSHClient.CommandFailed {
    // Missing error reason
    let message = "Command failed: `\(command)`, ExitCode: \(error.exitCode)"
    throw SessionError.executionFailed(message: message)
}

If you're interested in an output, rather than the convenience wrappers around it - look into executeCommandStream

Also noteworthy: #71 adds support for an stdin stream as well. But awaiting feedback
