humility ringbuf list table is misaligned when a ringbuf has a long path

[hawkw]

If the path to a ringbuf is longer than 30 characters, the ADDR and SIZE columns in the table printed by humility ringbuf list aren't aligned nicely. And, it turns out that when building Humility for a Gimlet, there are several ringbufs with paths longer than 30 characters:

Humility version:

humility 0.10.38

My guess is that the current lengths of these columns was selected to fit nicely in an 80-column terminal, which makes sense. But, when there are long paths, it's hard to read regardless of the terminal, and making the terminal wider doesn't help. We probably want to default to the current lengths, but scan the ringbuf paths first to see if there's any entry that's too long, and make it wider in that case?

Alternatively, since the address and size columns are almost always much shorter, we could just put them first, although I'll admit it's kinda weird to see the address and size without knowing what it is that you're looking at (as a right-to-left language reader)...
