feat: add resume command

Support resuming the last tracked activity.

When `hamster resume` is called, the last tracked activity is
started, i.e., the same activity is started again with the current
start_time.

If `hamster resume --continuous` (or short with `-c`)
is called, the last tracked activity continues to be tracked, i.e.,
its end_time is removed.
