Add daily/weakly time target

[robgal519]

Hi,
it would be nice, if I could set target for how long I want to work on a project.
Maybe I could set the time boundaries for the projects (for example form 9 to 5 I work for my company, and from 8 to 10 I work on my own side project). Further more I work only 3 days a week, so I would like to personalize those time boundaries on weekly basis.
Something like work-life balance, would be nice to have.

So when I reach my time goal, vscode will show a little popup.
Those time boundaries could be configurable in the extension setting. (after all, almost everyone will have the same schedule every week, and if not it is no big deal to change it in config)
