Support for extending existing Checks with business specific Checks

Is your feature request related to a problem? Please describe.
I would like to be able to add Custom Checks by only making changes in python-deequ and not in deequ (scala). As a team with no Scala knowledge, it would allow for greater efficiency and adoption.

Describe the solution you'd like
I'd like to be able to extend Checks with Checks specific to my business that would not be valuable to the community. For example, are the values in a column valid ISBN's?

Additional context
If there is a way to do this already, would you mind giving an example and I'll update the docs.

Thanks for your time.

Commencez par lire la Checks API existante et sa documentation afin de déterminer si Python expose déjà un point d’extension sans modifier la couche Scala Deequ. La tâche est terminée si vous fournissez soit un exemple documenté, uniquement en Python, d’un business check tel que la validation d’un ISBN, soit une implémentation délimitée prenant en charge ce type de checks.
