Make lower-casing of scope optional

[coldacid]

Using cz-conventional-changelog with non-JS projects where components and file names may be cased is problematic due to the forced lower-casing of the value typed in for the scope prompt. Lower-casing should be optional, although defaulting to on is fine.

According to the conventional-commits/conventionalcommits.org#24, the casing is not enforced and the only hard requirement is to be consistent.

I could try to get a PR working if you're interested in adding a configurable option for this.

I need to stick with v2 until this will be available since we need those uppercase letters at the front of the subject (because of reasons) :/
It'd be great if anyone came up with a workaround for this.

This PR has now merged and released in v3.1.0. Does this need closing?

[coldacid]

@ATLSAPI let me update and try it out.

Looks like this doesn't work on Windows when using a global install as Node will grab the 3.0.1 install out of commitizen itself rather than the side-installed 3.1.0 cz-conventional-changelog, unless an explicit full path is used in .czrc

[coldacid]

So apart from that caveat (which is more of a Node and commitizen config issue) it looks like the functionality itself worked. Since providing an absolute path to cz-conventional-changelog in .czrc works, I'd say that this issue is good and done. Closing.
