[Feature request] Line changes per hour/day/month/etc.

[FelixFourcolor]

I love the Git commits per [time] feature, and also that you keep track of the total line changes of each author in Contribution stats. Can you combine them together for a Line changes per [time] statistics?

I think it would be a nice feature, since it shows at which hour/day/month/etc. the repository is most active. The closest we have is git commits per [time], and although we all know LOCs is not a good productivity metrics, it's still more meaningful than the number of commits.
