Add option for filtering commits by path

[iloire]

I have three components in the same repository. It would be awesome if I could filter them by path (git log -- <path>), so I can generate three different CHANGELOG files (one for each component)

Any plans to add this? Would you accept a PR?

Yeah, that's a good idea! We'd absolutely be willing to accept PRs.

I think I feel comfortable enough to encounter that, and will give it a try.
One question though, what should we do if there is a conflict between this new subpath option and the output file option?
e.g. if there is also an output file specified in a different than the current folder. I thought to address that this way:

• If there is an explicit output file specified in a different path than the current directory --> I will use it as is
• If the output file left defaulted, or is designated to be in the current directory and there is subpath option set --> I will place/work on a file in that provided subpath

@iloire @robinjoseph08 Thoughts?

This tool is unusable in a monorepo without this feature.
