"errors" output is unsorted

[raphideb]

When I run the errors command, the output is not sorted by time, which makes it hard to figure out what's really going on:

pgweasel errors postgresql-Wed.log |cut -d' ' -f1-2
2026-04-29 04:24:31.476
2026-04-29 00:32:12.863
2026-04-29 03:55:24.187
2026-04-29 05:30:44.998
2026-04-29 02:27:21.288
2026-04-29 03:55:24.187
....

It can be sorted with sort but it'd be helpful if pgweasel would print the lines in order:
pgweasel errors postgresql-Wed.log |sort -k2 |cut -d' ' -f1-2
2026-04-29 03:37:52.080
2026-04-29 03:37:52.080
2026-04-29 03:37:52.088
2026-04-29 03:37:52.095
2026-04-29 03:37:52.109

Pls check, does branch #31 works for you.

Merged. Let's see. Hopefully it does not degrade perfomance a lot.
