feat(komorebic): add log command

This commit adds a log command directly to the komorebic cli to make it
easier for users to check the logs if they don't have tail installed or
are not familiar with it.

A separate logfile with ANSI color codes is now being written to the
user's tempdir, which is tailed by the log command until the process is
halted by a Ctrl-C signal.
