Feature Request: Ability to hide "Passphrase: ___" and show time

[bsdayo]

This is an awesome project! I've used it to encrypt some stuff. I have some feature requests:

• Add an option to hide the "Passphrase: ___" part. I don't really want to write my passphrase on paper, but having an empty fill-in-the-blank makes me feel uncomfortable. I'd like to have the option to leave it out.
• Add a display of the time so the paper can show at what point the file was encrypted. (Maybe also a option to control whether to enable this feature?)

Since I don't know Rust at all, there's no way for me to implement them and then submit a PR 😟. I sincerely hope you'll take my suggestions!

edit: Learned some basis about Rust and implemented in #89

btw another problem is that the text below the grey dashed line is not centered...? That asymmetry brings a strange feeling.

The fields/text below the QR code is more configurable as of v1.2.0 so it's now possible to have arbitrary text there.

e.g. paper-age --notes-label="Created at: $(date -Iseconds)" --skip-notes-line will add the current time to the PDF.
