Timer should have a finished state

Timer should have a finished state. Right now it's only possible to check this with a few checks, including the remaining time, which can go below zero (probably it should set itself to 0 instead of going below zero).

Hi, Thanks for opening the issue. Ignore the earlier comment and linked PR, it was meant for #13
I no longer actually maintain this library actively but if enough people are still using it, I might consider updating it with these requested changes.

If it's possible for you, you can open a PR yourself with your desired changes, and I will be sure to merge it!

timer split should show descending order and also should show time format. Please, can you add it?
