Structure(d) output of wg?

[Jason A. Donenfeld]

Hi Dan,

This already exists. While `wg show wg0` gives some hipster colorized
output, `wg show wg0 [CATEGORY]` gives very structured output meant
for parsing with bash or grep or sed or cut or whatever you want. For
example:

[zx2c4 at demo ~]$ sudo wg show wg0 bandwidth | tail
l8gKhi5rvJChhDWHl+C7Ubj8hSHfW0HbkOOA9GQPL3Y=    13272   43056
