Instead of logging tasks like 'start task1' and 'end task1', output will now be like '::group::task1' and '::endgroup::' when the -g flag is given. This should resolve #9 .

This should boost normalize-path's score on [skypack](https://www.skypack.dev).

It would be pretty cool if we could get information about network interfaces, their mac addresses, ip address, cidr, etc.
