Stopwatch command to pause

The /stopwatch command added recently in snapshots is great, however some improvements could be made.

A /stopwatch pause command would be nice to pause the stopwatch without resetting it.
Of course /stopwatch resume would also be added alongside it.

It would also be nice if when creating a stopwatch, you could choose whether the stopwatch pauses when the server is paused, something like /stopwatch create <id> [<pause_with_server>]
By default, <pause_with_server> would be false, like it is now.
Without this, datapacks would still need to use scoreboards and tick.mcfunction if a timer that pauses with the server is needed.
