Add Basic CLI

[Seniatical]

Instead of forcefully creating a changelog add a proper CLI, which comes with a help command and flags for creating a changelog.

Example Use of CLI

Thanks for this feature @Seniatical ! Having a proper CLI manager is definitely useful when we grow the tool to have diverging functionalities. For the moment, however, since generating in-project changelogs is the only featureset, doculog should be the default execution command - I don't want users to have to remember another flag in order to get the tool to run. I'll leave this open for a little bit while I think about the best approach though, as this might be useful for some other features. For example, maybe a --overwrite flag which ignores an existing changelog and generates from scratch?

This isn't an actual issue as I already left the "no arg" option empty, so getting it execute instantly isn't hard to implement

👍

Commented out CL flag, since there's no use for it as of now, but added the overwrite flag which deletes the CHANGELOG.md in the current dir allowing a fresh one to be generated

[Seniatical]

Done as requested from above, added path flag to modify which directory user wants to generate changelog for

is this still being worked on?
