Feature
* feat: add option to only parse commits for current working directory (509)
When running the application from a sub-directory in the VCS, the option
use_only_cwd_commits will filter out commits that does not changes the
current working directory, similar to running commands like
`git log -- .` in a sub-directory. ([`cdf8116`](https://github.com/python-semantic-release/python-semantic-release/commit/cdf8116c1e415363b10a01f541873e04ad874220))
