Secret decode

[aalsup]

This PR contains a new keybinding for char('x'). When viewing secrets, this new handler logic allows the user to see the base64-decoded secret contents.

Awesiome! Thanks. Could you add one or two tests for the decoding part please

[aalsup]

I've added a test -- test_decode_secret. I've also done a little cleanup to make clippy happy. Let me know if you'd like me to change the way its implemented. I wasn't sure where exactly to put the handler for decoding the secret, so I put the logic within the handle_describe_or_yaml_action() function - possibly not the ideal place, but it does work.

Great work 👏
