Removing expiry dates for TOFU

[colecmac at protonmail.com]

Hello all,

Mozz proposed an interesting idea to me on Github, which was removing expiry dates
from TOFU entirely.

I wrote a quick post on it, I'd appreciate it if you could read
it and offer your thoughts. I think this could help make things more secure on
Gemini, and possibly make TOFU and cert management more painless.
