[Enhancement] [Bugfix] Grab Git History Automatically

[kevinmatthes]

This patch introduces the automatic reading from Git itself. It thereby fixes #16 and replaces the feature request from #3.

I would also squash the last 4 commits and the first two! While you have now (almost) all changes in one commit each, I think, those changes could still be considered too small sub parts of the actual problem. At least in my opinion. 😅

Since this is a branch on its own, merging on squash will combine all of them to a single one.

While this is true, I would prefer if you tried to improve your commit sizes. It makes reviewing easier, especially, if you do it on per commit basis, and it would also be nice to simply merge the commits in to the main branch, to have a better overview over the commits. Ironically, tools like this, would profit from this. 😄

Users now need to specify a source to read from. This might be either the local Git history (--git) or an input file (-i). stdin will be added later, perhaps with an option, as well, such that a call without options will redirect to the help overview.
