Add an option to enter scope of changes in a commit

Hello @carloscuesta!

Recently, folks at our organization shifted from Commitizen to gitmoji-cli for commits for more readable commit messages and also because it just looks better! But we had one minor problem, i must say feature request, on the gitmoji cli. It would be better if we had an option to add scope to the commit message which helps us a lot in finding commits related to specific changes or when we want to see what changes were made in specific parts of our code base.

Issue: No scope option makes it difficult to understand which parts of the entire repository / code base has changed. For example, if there are two different parts ( let’s say, two Reactjs components or two different templates in a python django project, or two different kinds of services and/or independent or dependent parts of an application, etc ) which might have similar changes but on different commits, we can have same commit messages but with additional scope information which could be easier to read. This is not available currently on gitmoji-cli.

Something like this :

Raised a PR ( #139 ). Please review and add it as a feature to gitmoji-cli! Thanks!
